✯Question✯

• A train 270m long is running at 80km/hr. How much time will it take to cross a platform 13m long​ ?

✭Given✭

• Distance travelled by a Train = 270m

• Speed of a Train = 80km/hr

✦To find✦

• How much time will it take to cross a platform 13m long ?

✩Solution✩

• Total distance to be travelled = Distance of Train + Distance of Platform
• 270m + 13m
• 283m
• Speed = 80km/hr       ( convert to m/s )
• Speed = 80 × ⁵⁄₁₈
• Speed = 22.22m/s  ( or )
• Speed = ⁴⁰⁰⁄₁₈ m/s

• Time taken = Distance ÷ Speed
• Time taken = 283 ÷ ⁴⁰⁰⁄₁₈
• Time taken = 283 ÷ ²⁰⁰⁄₉
• Time taken = 6288.88 s

✱The time taken by the train to cross the platform is 6288.8 s
