Question

Please help me with this homework

Answer 1

Step-by-step explanation:

Average speed of a body in motion is the rate of change of distance per unit of time.

This is expressed as;

Average speed =
`(Distance )/(time)`

1. Distance = 5000m

Time = 50s

Average speed =
`(5000)/(50)` = 100m/s

2. Distance = 300m

Time = 100s

Average speed =
`(300)/(100)` = 3m/s

3. Distance = 550m

Time = 120s

Average speed =
`(550)/(120)` = 4.58m/s
