Two trains 100 m and 170 m long respectively are approaching towards each other on a same track met with a crash in 3 seconds. If before 3 seconds, the distance between them was 621 km and the speed of the faster train is 114 m/sec, find the speed of slower train.

100 m/s
87 m/s
95 m/s
93 m/s
None of these

Validate

Solution:

Let the speed of the slower train = x m/sec

{621}/{x+114}

= 3
621 = 3x + 342
3x = 279
x = 93 m/sec.
