Question

If the fastest you can safely drive is 65 mi/h, what is the longest time you can stop for dinner if you must travel 541 mi in 9.6 h total?

Answer 1

Tt = D / S = distance / speed = time to travel 541 mi

T1 = 541 mi / 65 mi/hr = 8.32 hrs

if it takes 8.32 hrs to travel 541 mi then that leaves

9.6 - 8.32 = 1.28 hrs for non-travel time
