Question

A train of length 500 metre equal along east direction with 15 metre per second. A bird is moving above it along west with speed 10 metre per second then find out the time taken by the bird to cross the train.​

Answer 1

Step-by-step explanation:

Given

Length of train = 500 metre

Speed of train = 15 metre per second in east direction

Speed of bird = 10 metre per second in West direction

According To Problem

=> Vr = Vt + Vb

=> Vr = 10 + 15

=> Vr = 25 metre per second

Now we know that

Speed = distance \ time

So time = Distance \ speed

=> Time = 500 \ 25

=> Time = 20 seconds

Hence

Bird will cross train in 20 seconds
