Question
5 out of 35
 

A train 120 m in length passes a pole in 4 second and another train of length 225 m travelling in the same direction in 15 second. Find the speed of second train?



A 8 m/s
B 7 m/s
C 12 m/s
D 22 m/s
E 32 m/s

Ans. B

Speed of train = m/s

Total distance = 225 + 120 = 345 m

Relative speed = m/s

But the speed of 1st train is 30 m/s.

So, speed of 2nd train = 30 – 23 = 7 m/s
