A bus covers a certain distance at 60 km/h and returns at 40 km/h. If the total time is 5 hours, what is the distance of the one-way trip?
Show answer & explanation
Correct answer: B
Explanation
Let's assume the distance in one direction is D km.
Going time
Speed = 60 km/h
Time = D/60
Returning time
Speed = 40 km/h
Time = D/40
Total time =
D = 120
Distance in one direction = 120 km
