Question

a train running with 54km/hr what time taken by train to cross 90 m platform​

Answer 1

Step-by-step explanation:

speed of train =54km/h=54x5/18m/s

=15m/s

distance=90m

so time taken=distance/speed

=90/15=6s

Answer 2

speed of the train = 54km/h = 54×5/18m/s =15m/s

length of the platform =90m

hence required time = 90/15=6s.
