Without stoppages, a passenger train runs at an average speed of 120 km/h, whereas with stoppages, it runs at an average speed of 80 km/h. What is the total time taken by the train for stoppages on a route of length 480 km?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 2 hours.
Time (no stop)= 480/120 = 4 hours
Time (with stop) = 480/80 = 6 hours
Time (stoppages) = 6 − 4 = 2 hours
