Question

7.) A bowler throws a cricket ball at a speed of 120 km/h. How long does this ball take to travel a distance
of 20 m to reach the batsman?​

Answer 1

Step-by-step explanation:

Speed of the cricket ball =120 km/hr

60

120×1000

m/min

2×1000

2000 m/min

Now, speed in m/s=

60

2000

=

6

200

=

3

100

So, 20 m can be covered in =

3

100

20

=

100

60

=0.6 s

Answer 2

● Speed of ball = 120kmph

OR 120×1000mph (°•° 1km=1000m)

OR 120000m/60×60s (°•° 1hr=60×60s)

OR speed of ball = 33.33mps

● distance = 20m

•°• Time = distance/time

so, time is 20/33.33 s

time = 0.60s

This is your answer.
