How long will a train 100m long and travelling at a speed of 45 km/h , take to cross a platform of length 150 m ? |
|
Answer» Speed = 45 km/hr.Length of train = 100 m Length of platform = 150 m.⠀To find:-The time taken to cross the platform.⠀Solution:-★The TOTAL distance NEED to be covered:-→ 100 + 150 → 250 m ⠀→ Speed = 45 km/hr → Speed = 12.5 m/s⠀★Formula used:-Time = Distance/speed⠀→ Time = 250/12.5→ Time = 20 sec⠀Hence,the time taken to cross the platform is 20 seconds. |
