Question

1. John is a runner. He runs the 100m sprint in 10.6s. What speed did he travel at? (in m/s) *

Answer 1

Answer:

distance=100m time=10.6second speed=distance/time 100/10.6=500/53= 9.43396

Answer 2

Given:

Distance traveled by John in the sprint= 100 meters

Time is taken by John to complete the sprint= 10.6 seconds

To find:

Speed of John during his sprint=?

Solution:

Speed is a quantity that depends on the distance reached by an object in a given period of time.

The speed of John during his sprint can be calculated from the given formula:

=> Speed = $\frac{Distance (metres)}{Time(seconds)}$

=> Speed of John during sprint = $\frac{100 metres}{10.6 seconds}$

=> Speed of John during sprint = $\frac{100 metres * 10}{106 seconds}$ (To remove decimal from denominator both the numerator and the denominator is multiplied with 10)

=> Speed of John during sprint= $\frac{1000 metres}{106 seconds}$

=> Speed of John during sprint= 9.433 meter/seconds.

Hence, the speed of John during his sprint was 9.433 m/s.
