campbell_st · Answer

well 1500/50 = driving time

not driving time = 42 - answer above

anonymous · Answer

The 42 hours with reststops is just extra information. Since you are going 1500 miles away and driving at an average of 50 miles per hour while you were driving all you would do is divide 1500 by 50 which would be 30 miles total driving (that would mean you speant 12 hours at rest stops 42-30=12)

texaschic101 · Answer

Distance = Speed * Time....but since we are looking for time, it can be chaned to D/S = T

D/S = T
distance (D) = 1500
speed (S) = 50
now sub
1500/50 = 30 hrs

so if your actually driving 30 hrs and your trip took 42 hrs......42 - 30 = 12 hrs  not driving
