A train without stoppage travels with an average speed of 80 km/h and with stoppage, it travels with an average speed of 64 km/h. For how many minutes does the train stop on an average per hour? Correct Answer 12

Given:

A train without stoppage travels with an average speed of 80 km/h and with

stoppage, it travels with an average speed of 64 km/h

Calculation:

Without stoppage average speed = 80 km/h

With stoppages average speed = 64 km/h

As we know,

Time of rest per hour equal to the difference in average speed divided by the

speed without stoppage.

Required time = × 60 = 12

Hence, the train stops on an average 12 minute/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.
