explanation:

we have

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

a.t.q.

=> vr = vt + vb

=> vr = 10 + 15

=> vr = 25 metre per second

speed = distance \ time

so time = distance \ speed

=> time = 500 \ 25

=> time = 20 seconds

therefore

bird will cross train in 20 seconds
