A train crossed a platform in 45 seconds travelling with a speed of 36 km/h. If the length of train is 200 meters, then what will be the length (in meters) of the platform?
Solution
Correct Answer: Option A
Speed = 36 km/hr
= (36 × 1000)/3600 m/s
= 10 m/s
In 45 seconds, the train travelled = 45 × 10 m = 450 m
length (in meters) of the platform = 450 - 200 = 250 m
= (36 × 1000)/3600 m/s
= 10 m/s
In 45 seconds, the train travelled = 45 × 10 m = 450 m
length (in meters) of the platform = 450 - 200 = 250 m
