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?
