E. None of these



Relative speed of the train with respect to the motorbike should be the speed with which the length of the train is covered in 40 secs.

Calculate the relative speed => 100 - 64 = 36kmph and time is 40 sec = 40/3600 hrs
Distance (in this case the length of the train ) = S*T = 36*40/3600
.4km or 400meters.

So Answer (A)

Please suggest if this is correct.

The train is overtaking the motorbike. That means they are traveling in the same direction. Relative speed is the difference of 100 and 64, which is 36 kmph.
Converting to mps we get 10 mps.
Speed*time= distance
10*40 = 400 meter is the length of the train.

Relative speed of the train with respect to the motorbike in order to overtake it is = 100 - 64 = 36 kmph = 36 *\(\frac{5}{18}\) m/s = 10 m/s
Distance covered will be equal to length of train as length of the motorcycle will be negligible compared to length of the platform
So distance = 10 * 40 = 400 metres
Correct Answer - A




P.S.- for converting speed from kmph to metre/second multiply by \(\frac{5}{18}\)
similarly for converting metre/second to kmph multiply by \(\frac{18}{5}\)

E. None of these

Train overtakes a bike means that we are talking about total length of the train. (train's head is close to bike when it started and its tail crosses the bike when it overtakes the bike)

Relative speed= 100-64= 36Km/h = 36000 m/h

time= 40 seconds

Distance= speed*time

36000* 40/3600= 400 meters.

A is the answer.
