Maths question

#1
Alright chaps just a quickie.
As advised by rab in another topic i measured my running distance online using the measuing tool on google earth. Bloody good program it is to, i found that ive been running 1.74 miles instead of the 1.5 i had thaught it was. Last night i ran the 1.74 miles in 10 mins 36 secs, but its not 1.5 miles.
Im just wondering if someone could explain to me how this would be worked out. I.e. how do i scale it down to what the time would be if i was running 1.5 miles? How many seconds do i take off etc?
Would be much obliged if this could be explained to me for future reference as im proper crap at maths.

Brad,

You truely are a useless fcuker if you cannot work that out.....

I'll give you a tip. You're also shite at grammar.

Well 1.74 is 116% of 1.50. 10.36 is 636 seconds. Erm. 548 seconds is what you'd have done 1.5 miles in?! I dunno, erm, I think that's right, someone else check that answer. I wasn't bad at maths, I normally used to pull the right answer from somewhere.

548 seconds is 9 minutes 8 seconds.

10 min 36 sec = 636 seconds.

Divide this figure by 1.74.
Multiply the resulting figure by 1.5.
The figure you get should then be divided by 60.

Round up the resulting figure to get your approximate 1.5 mile timing.

Don't be a lazy fcuker. This is BASIC stuff. :x

Your time, divide by 1.74 and then multiply by 1.5.

Edit: Yeh, what ^ he said.. /Edit

Forks,

You're not far out. It's 9.14 rounded up but I am ASTONISHED (seriously) that an 18 yr old is unable to work this out.......

Sorry Matelot, but the .14 relates to 14% of a minute, being.......8.4 seconds, rounded down to 9mins 8 Secs.


Pedant out!

1.74 miles in 10.36 mins.

Break the timing down to seconds (636)

Divide 636 by 1.74 (unit time)

Ans = 365.51724137931034482758620689655

Divide this by 100

Ans = 36.551724137931034482758620689655 (time for 100th of mile)

Multiply this by 150 (desired unit)

Ans = 548.27586206896551724137931034483

Divide this by 60 (convert to mins)

Ans = 9.1379310344827586206896551724138

Or 9 mins 13.7 secs for the 1.5 mile.


Or, if I was thinking (or reading Dukes) 13.7% of 1 min = 8 seconds!

Too early in the week!

I'll take the mess revolver and do the decent thing! I did do it in my head though so apologies.

But seriously, this really irritates me. I have known engineering graduates who are just as bad though....

Easy peasy.

Time taken = 636 secs
Distance = 9187 feet
Speed = 0.069228257320126265374986393817351 fps.

Distance you want = 7920 feet
Speed = 0.069228257320126265374986393817351 fps.
Time taken = 548.28779797540002176989223903343 seconds

Result = Too slow, more running required.
:D


9 mins 13 secs.

Hopefully ill grow up to be as smart as you matelot, and im 17 not 18, and as i said im not so good at maths - im not so good at most things acedemic really thats one of the reasons im joining the army.
Thanks for answering this *basic* question though, maybe one day you will be able to do it without having to take the piss out of someone because they aint so smart. knob.

Lots of people would not be able to work it out. If we were all really really clever then we would all be able to spell truly, wouldn't we?

Hey, are we talking standard imperial miles or PTI/DS it's only another mile miles.

There is a feck of a difference! Usually a couple of miles(imperial)

Or an extra ringpiece for respiration!!

Works both ways - several years ago, i was amazed at my BFT time of sub 8.30 for the 1.5, and at the point where the unit lardarse crossed in 9 something alarm bells rang. Queue, PTI looking very guilty whilst staring at the odometer on his LandRover 110 - Kilometres anyone?!

Floppy, I should really check my spelling shouldn't I??? :D

Brad,

I'm not having a go at you about intelligence. Just simple things really. Break stuff down, look at it in an analytical way. 10 m 36-break it down-636 seconds. It makes it easier that way.

When it comes to algebra etc, I'm hopeless at it. But lets be brutally honest here. We're talking about basic division and multiplication-stuff that you should've mastered long before the age of 17 IMO. Basic maths is essential for most things-map reading for example. If you're geniunely struggling that much, may I suggest that you go to WH Smiths/Waterstones etc and buy yourself a basic teach yourself maths book and spend less time on Internet Chat forums?

And sort out your attitude whilst you're at it. I'm speaking as a senior when I say how bloody annoying it is when people come up to me and struggle with the basics-I haven't got a problem helping them at all but sometimes I get disheartened when I've got lads who are 1 maybe 2 years younger than me (I'm 26) struggling to grasp rudimentary things which should've been mastered early in life.

The days of someone joining the forces because they say they're academic underachievers are slowly disappearing. Go into any trade in the Army/RN/RAF and see how far that attitude will get you. Enthuasism combined with a lack of ability can only get you so far.

Of course, if your heart is set on a career in the Military Police, then disregard my last.... :wink:

A billion apologies for bringing this back up, but i have yet another question that will probobly be called obvious and i will probobly be called an idiot. So belive me when i say i have been trying all day to work this out.
i have decided to divide my 1.5 mile run up into thirds. so half a mile. And as im aiming to run 10 mins 30 seconds on this new harder route im running i have had to divide the 10 mins 30 seconds by 3.
10.30/3 = 3.43
so 3.43 to every half a mile? This means that after my first half mile i know that if im below this time i know im ok and if im above it i need to pick up the pace.
I also need to know the time i need to be running after another half mile, ie - a mile
so 3.43 X 2 = 6.86 Obviousely only 60 seconds in a min, so i figured it was actually 7 mins 26 seconds.
But then if you were to add the original 3.43 to the 7.26 you would get 10.69 - not 10.30.
So obviousely ive gone wrong somewhere, ive been using basic number calculater on me phone that does not deal with time ratio so that may be the problem.
If its a really simple answer then i apologise, as i said before maths is not my strong point, but any help, even in a PM would be much obliged.

It may be easier if you break it into seconds as suggested previously 10:30 = 630 seconds, so 0.5 miles = 210 seconds.

However, IMHO I wouldn't get to bogged down with having to run your first 0.5 miles in xx seconds just as long as you can get under (hopefully at your age well under) 10:30.

Leave statistics to the geeks, and just get your trainers on fella.

You need to make the time into minutes Bradders. 10mins is 60 (secs) x 10 = 600 then add the 30 secs which gives you 630 seconds. Then divide 630 by 3 (which is your 1/3 of a mile) which gives you 210 seconds then you need to make this back into minutes which is 3mins 30seconds. and not the 3.43 you came up with as your calculator will work on a default 100 not the 60 measure you require.
