Question

A train 350 m long is travelling with a uniform speed of 45 km h'. How much time will it take
to pass a 250 m long bridge.​

Answer 1

Answer:

48 seconds

Step-by-step explanation:

Length of the bridge= 250 m

Length of the train= 350 m

So the total length it has to cross to cross the bridge = length of the bridge+length of its own body

= 250+350 m

= 600 m

= 0.6 km

Now according to the question,

The train crosses 45 km in 1 hour

So " " " 1 km in 1/45 hour

Thus " " " 0.6 km in (1x0.6)/45 hour

= 0.013333 hour

= 0.8 minute

= 48 seconds
