Question

A train 240m long is running at a speed of 90km/hr. How much time will it take to cross a platform 160m long.

Answer 1

Answer:

HELLO!!

For crossing the platform completely it must cover the distance of platform as well as length of its own..

r crossing the platform completely it must cover the distance of platform as well as length of its own..so the total distance is 240 + 160 = 400

r crossing the platform completely it must cover the distance of platform as well as length of its own..so the total distance is 240 + 160 = 400change the velocity in m/s so u will get 25 m/s

so speed = distance / time

so speed = distance / timeso time = distance/ speed

so speed = distance / timeso time = distance/ speedtime = 400 / 25

so speed = distance / timeso time = distance/ speedtime = 400 / 25time = 16 seconds..
