Question

A Sprintes completes his 100m
sprint in 12 seconds .
Calculate
his speed.​

Answer 1

Step-by-step explanation:

Given :

• A sprinter completes his 100 m sprint in 12 sec.

To find :

• Speed of the sprinter.

Solution :

We know:

=> Speed = Distance/Time

Substituting we get:

=> Speed = 100/12

=> Speed = 8.33 m/s

Verification :

Distance = Speed × Time

=> 100 = 8.33 × 12

=> 100 = 9.96 {Approximately 100}

=> 100 = 100

∴ L.H.S = R.H.S

• Hence, the sprinter is moving with a speed of 8.33 m/s.
