Question

The speed of the train is 54km/h. if If the length of the train is 123 m then 177 m to cross the long platform It will take time.​

Answer 1

Answer :-

GIVEN

Speed of the train = 54km/h

In m/s = 54 × 5/18

=> 15m/s

Length of the train = 123m

TO FIND

Time taken by the train to cross a platform which is 177m long

SOLUTION

Total Length = length of train + length of platform

= 123m + 177m

= 300m

we know,

Time taken = distance/ speed

= 300m / 15m/s

= 20 s

Therefore time taken for the train to cross the platform = 20 sec
