The average speed of a train without stoppages is 48 kmph and average speed with stoppages is 40 kmph. How many minutes in an hour the train stops on an average?

5 min

7 min

8 min

10 min

Explanation:

If the train were to travel without stoppages, it would cover 48 km.

With stoppages, the average speed reduces by (48-40) = 8 km

Therefore, (8/48)* 60 minutes = 10 minutes

10 minutes would be the time per hour the train stops on an average.

Hence, option 4 is the correct answer.
