Question

A train 27 M long is running at 80 km /hour how much time will it take to cross a platform 130m long

Open in App
Solution

Total Distance to be covered =
Length of the train + length of the platform
=27m+130m
=157m

Speed=80 km/hr
=80*5/18m/s
=400/18m/s

Time taken = Distance/Speed
=157m÷(400/18 m/s)
=157*18/400 s
=7.065 s.
