Question :–

A bowler throws a cricket ball at a SPEED of 36km/hr. How long does this ball take to travel a distance of 20 METRES to reach the batsman?

Given :–

  • A bowler throws a cricket ball at a speed of 36km/hr.

To Find :–

  • How long does this ball
  • take to travel a distance of 20 metres to reach the batsman?

SOLUTION :–

First, change km into m.

→ 36 \times \frac{ \cancel{10} \cancel{00}}{ \cancel{36} \cancel{00}}

→ \cancel{36} \times \frac{5}{ \cancel{18} }

→ 2 \times 5

→ 10 \: m/s

Now,

Time taken to travel 20m in the speed of 10m/s.

→ \frac{ \cancel{20}}{ \cancel{10} }

→ \boxed{\tt\orange{2 \: sec}}
