Question

How long will it take a boy running at 5 km/hr to cover a distance at 500 metre?

Answer 1

Given:-

• Speed = 5 km/hr

• Distance = 500 m

To be calculated:-

Calculate the time taken.

Formula used:-

Speed = Distance/Time

Solution:-

We need to convert the speed of boy from km/hr to m/s

1 km = 1000 m

5 km = 5000 m

And,

1 hour = 3600 seconds

So,

5 km/h = 5000/3600

= 1.38 m/s

Now,

Speed = Distance/Time

★ Putting the values in the above formula,we get:

⇒ 1.38 = 500 / Time

⇒ Time = 500/1.38

⇒ Time = 50000/138

⇒ Time = 362.31 seconds

Hence,the time taken by boy is 362.31 seconds.
