Question

Two trains are travelling in the same
direction at 70 kmph and 50 kmph. The
faster train passes a man sitting in the
slower train in 36 seconds. What is the
length of the faster train?​

Answer 1

Answer:

We know that speed of fast train is 70Km/hr = 19.444m/s

And speed of Slow train is 50Km/hr = 13.889m/s

Time given faster train passing slower train in 36sec

We know that two trains are travelling in same direction

So, 19.444 - 13.889 = 5.555m/s

By applying Distance = speed×time

= 5.555×36

= 199.98m.
