Question

A sprinter travels a distance of 300 m in a time of 28.22 seconds. What is the sprinter's average speed rounded to 4 sf?

Answer 1

10.63m/s

Explanation:

distance traveled=s=300m

time taken=t=28.22s

average speed=v=?

average speed=
`(distance covered)/(time taken)`

average speed=
`(300m)/(28.22s)`

average speed=10.63075m/s

now in the question it is said that round to 4 significant figures so will write only first four digits

average speed=10.63m/s

Answer 2

`10.6 \: m/s`

Explanation:

Average speed = distance covered divided by the time taken.

`S=(d)/(t)`

`(300)/(28.22)`

`=10.63075`
