A train of length L move with a constant speed Vt. A person at the back of the train fires a bullet at time t = 0 towards a target which is at a distance of D (at time t =0) from the front of the train (on the same direction of motion). Another person at the front of the train fires another bullet at time t = T towards the same target. Both bullets reach the target at the same time. Assuming the speed of the bullets, Vb, are same, the length of the train is

we may assume that, when the person at the front of the train fires the bullet
the bullet fired by the person at the rear end has just reached this men
therefore;
using concept of relative velocity
T=(lengthof the train)/(Vb-Vt)
