Question

A train running at the speed of 36 km/hr crosses a bridge of length 100 meters in 14 seconds. What is the length of the train?​

Answer 1

Answer:

1300m

Step-by-step explanation:

1hr=60mins=3600s

3600÷ 36=100

Total length=14x100

=1400

Ans:1400-100

=1300m

Answer 2

Step-by-step explanation:

speed of train=v=36km/hr km/hr=10m/s

Let x metre be the length of train

Total distance to be traveled by train to cross the bridge =(x+100)m

As distance=speed × time

there for (x+100) = 10 × 14

x = 40m
