Question

A train running at the speed of 72 km/hr passed a man in 14 sec and a platform in 32 sec. Find the length of the platform?

Answer 1

this is the answer do let me know if it's correct or not

Answer 2

Convert km/hr to m/s.

72km/hr= 20m/s

Distance = Speed × Time

So length of train = 20× 14= 280m

Now length of platform+ lenghth of train= 20× 32= 640m.

So lenghth of platform = 640-280= 360m...
