A train travels at a speed of 70 km/h without a stop and with a speed of 63 km/h with a stop. How many minutes does the train stop on an average per hour?

A train travels at a speed of 70 km/h without a stop and with a speed of 63 km/h with a stop. How many minutes does the train stop on an average per hour? Correct Answer 6

Given:
The train's speed is 70 km/h without stoppages and 63 km/h with stoppages

Formula used:

Speed = Distance/Time

Calculation:

Let the distance be 630 km(LCM of 70 and 63)

Time without stoppage = 630/70 = 9 hours

Time with stoppage = 630/63 = 10 hours

Difference in time 1 hour = 60 minutes

∴ Average stoppage per hour = 60/10 = 6 min/hr.

There is only one rail track between stations A and B on a railway line. One hour after the northbound superfast train N leaves station A for station B, the southbound passenger train S reaches station A from station B. The speed of superfast train is twice that of express train E, while the speed of passenger train S is half of that of train E. On some one day train N leaves from station A to station B 20 minutes late than its usual schedule. Both Train N and Train S have increased their speed to maintain the schedule as per the table. If the superfast train doubles its speed, then what should be the ratio (approximately) of the speed of the passenger train to the speed of the superfast train so that the passenger train reaches the station on that day at the exact scheduled time.
