Question

2. A train travels 100 m long moving on a straight level track passes a pole in 5 s. Find (a) the speed of the train (b) the time it will take to cross a bridge 500m long​

Answer 1

Answer:Distance covered by train in 5 seconds = 100m

Distance covered by train in 1second = 100/5 = 20m.

So Speed of the train is 20m/sec.

ii)

Distance = 500m

Speed = 20m / sec.

Time = ?

Speed = d/t

t = d/speed

Time = 500 ÷ 20

= 25 seconds.
