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 = [tex]\frac{Distance }{time}[/tex]
1. Distance = 5000m
Time = 50s
Average speed = [tex]\frac{5000}{50}[/tex] = 100m/s
2. Distance = 300m
Time = 100s
Average speed = [tex]\frac{300}{100}[/tex] = 3m/s
3. Distance = 550m
Time = 120s
Average speed = [tex]\frac{550}{120}[/tex] = 4.58m/s
