Answer 2

Given :--

The a train covers 20 meters per second

To Find :--

Speed of train in the unit of km/hr.

Now,

If it covers 20m in 1 second then in 1 minute it will cover 1 × 60 = 1 minute

20 × 60 = 1200m

Means that it covers 1 km 200 m in 1 minute.

Now,

If it covers 1200m in 1 minute then in 1 hour it will cover 1 × 60 = 1 hour

1200 × 60 = 72000 metres

Now, as we know that 1 km = 1000 m

Then, 72000 m = 72000 ÷ 1000

= 72 km (ans)

Therefore, it's speed will be 72km/hr
