DSSSB AE Civil Tier 1 Mock Test - 5 - Question 3

Without stoppages, a train travels with an average speed of 40 km/hr, while with stoppages, it covers the same distance with an average speed of 30 km/hr. What is the time (in minutes per hour) for which the train stops?

Detailed Solution for DSSSB AE Civil Tier 1 Mock Test - 5 - Question 3

Let the distance be the LCM of 40 and 30, i.e. 120 km.
So, without stoppages, time taken by train = 120/40 = 3 hr
With stoppages, time taken by train = 120/30 = 4 hr
Thus, in a total time of 4 hours, duration for which the train stops = 4 - 3 = 1 hr
Thus, in a total time of 1 hour, it would stop for 1/4 hour, i.e. 15 minutes.
