Question

an express train 240m long is running with a speed of 108km/h
in what time will it pass an electric pole​

Answer 1

240 m = 240 ÷ 1000 = 0.24 km

Time = Distance ÷ Speed

Time = 0.24 ÷ 108 = 1/450 hour

1/450 hours = 1/450 x 60 mins

1/450 hours = 2/15 mins

2/15 mins = 2/15 x 60 seconds

2/15 mins = 8 seconds
