Answer 1

Question :–

A train, 500 metre long, running at a uniform speed, passes a station in 35 seconds. If the length of the platform is 221 metre, the speed of the train in km/hr is ?

Answer :–

74.16 km/hr

Given :–

• Length of train = 500m long.
• Time taken = Passes a station in 35 seconds.

To Find :–

If the length of the platform is 221 metre then,

• Find the speed of the train in km/hr.

Solution :–

Total Distance travelled = Length of platform + Length of train

= 221 + 500

= 721m

Hence,

The speed of train = $\frac{Total \: distance \: travelled}{Time \: taken}$

= $\frac{721}{35}$

= $20.6 \: m/sec$

For convert m/s into km/h :–

Multiply the speed by 3.6,

So, we get,

= $20.6 \times 3.6$

= $74.16 \: km/h$
