A train’s speed including stoppages, is 10 m/sec and 15 m/sec excluding stoppages. For how many seconds does the train stop per minute?
(A) 10 sec
(B) 15 sec
(C) 20 sec
(D) 8 sec

Answer: (C)

Explanation: speed of the train excluding stoppages = 15 m/sec

speed of the train including stoppages = 10 m/sec

Loss in speed when including stoppages = 15-10 = 5 m/sec

=> In 1 second, train covers 5 m less due to stoppages

Hence, time that the train stop per second = time taken to cover 5 m

=distance/speed=5/15 sec =1/3 sec

So, in 1 sec it stops for 1/3 sec

  • in 60 sec it will stop for 60/3 = 20 sec.
