Question

A train running at a speed of 90km/hr crosses a platform double its length in 36 seconds.What is the length of tge platform in meters?

Answer 1

Answer:

600 metres

Explanation:

length of train = x

length of plattform = 2x

speed of train = 90 km/h

speed of train in m/s = 90*5/18

=25m/s

distance covered in 36 seconds = 25*36 = 900 m

3x=900

x=900/3

x=300

length of plattform =2x

=2*300

=600 m
