Answer:
A 450 m long train travelling at a constant speed of 60 km/h cross a man standing on 100 m long platform is 33 sec.
Step-by-step explanation:
Length of the train is 450 m.
Speed of the train is 60 km/hr= 60 x 5/18m/s =50/3 m/s.
Length of the platfom is 100 m.
We know speed=distance/time.
Total distance to cover 450+100=550 m.
using the above formula,we get
time=550/(50/3)
=33 sec.
