Question

21. If a 100 m long train crosses a bridge of
length 10 m in 22 seconds, then the time
taken by the train to cross a pole is?​

Answer 1

The formula to calculate velocity is = distance / time

(v = d/ t )

V velocity ; D distance ; T time

1. distance = 100 m ; Time = 10 seconds
2. velocity = 100 / 10 = 10 m /s

Or 3. 10 × 18/5 = 36 km /h
