A 300 meter long train moving with an average speed of 126 km/hr cross...
Speed of the train =126 km/hr =126×5÷18=35 m/s
Time taken to cross the platform =24 s
Length of the train =300 meter
Suppose the length of the platform =x

Distance travelled = speed × time
(300+x)=35×24=840x=840−300=540(300+x)=35×24=840x=840−300=540

Length of the platform is 540 meter which the man crosses in 55 minutes(300 seconds)
Therefore, required speed = 540÷300=1.8 m/s
