On my ammunition technition challenge one question is how far it will take to travel 484km at a speed of 55km per hour. I know it is going to be under 9 hours but can't figure at how many mintures, so I can't say it will be, 8hours and ?? minutes. Is is acceptable to put "It will be just under 9 hours" or something along those line ? Edit: Never mind, forgot to add in rest break times.
