Question

a train 270m long is running at 80km/hr . It takes 18 seconds to cross a platform find the length of the platform​

Answer 1

Step-by-step explanation:

Speed of the train = 80 km/hr = 80 x 1000/3600 80 x 5/18 = 200/9 m/sec

Distance = length of the trian + length of the platform = 130 m + 270 m = 400 m

Time = Distance / Speed

= 400x9 / 200

= 2 x 9

= 18 sec.
