Answer 2

$\bf{\underline{Question:-}}$

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

$\bf{\underline{Given:-}}$

• Bowler through a cricket ball at a speed of 36 km/h
• how long does this ball take to travel a distance of 20metres to reach the batsman??

$\bf{\underline{Solution:-}}$

• 1st we have to change 36km/h into m/sec

So,

$\sf → 36×\frac{5}{18} m/sec$

$\sf → 10m/sec$

• Time taken to reach 20 metre

$\bf\large → speed = \frac{Distance}{Time}$

$\bf → Time = \frac{distance}{speed}$

$\bf → Time = \frac{20}{10}$

$\bf → Time = 2m/sec$

$\bf{\underline{Hence:-}}$

• Ball take 2sec to travel a distance of 20m
