Q. A 100 m long train crosses a 200 m long platform at a speed of 30 m/s. How much time will it take to completely cross the platform ?

Formula: Time to Cross Platform = (Length of Train + Length of Platform) ÷ Speed of Train

T = L₁+L₂/V 

• L₁ = Length of train


• L₂ = Length of platform


• V = Speed of train

Solution:

Train length (L₁) = 100 m
Platform length (L₂) = 200 m
Train speed (V) = 30 m/s

Ans: 10 seconds
