Question

a train 200 metres long and travelling at a speed of 60 kilometre per hour will cross a pole in​

Answer 1

TIME TAKEN BY TRAIN TO CROSS THE POLL IS SAME AS THE TIME TAKEN BY TRAIN TO CROSS ITS LENGTH WITH ITS SPEED

SPEED = 60 KM / H
= 60 × 5 / 18 M / S
= 50 / 3 M / S

DISTANCE = 200 M

TIME = DISTANCE / SPEED
= 200 / 50 / 3
= 200 × 3 / 50
= 4 × 3
= 12

ANSWER

IT WILL CROSS THE POLE IN 12 SEC
