Given: Length of train = 500 m Length of platform = 1300 m Speed of train =216km/hr=216×(5/18)m/s ⇒ 60 m/s Formula used: Time taken = Total distance to be covered/Speed of train Calculation: Total distance to be covered =(500+1300)m ⇒ 1800 m Time taken to cross the platform =1800/60 seconds ⇒ 30 seconds ∴ The time taken to cross the platform is 30 seconds
