Answer:
A. 16.67 m/s
Explanation:
Speed or velocity refers to the rate of change in distance over a change in time. That is;
Speed = Distance ÷ time
Where;
Speed is in metre/seconds
Distance is in metre
Time is in seconds.
In this question, Steve throws a football 50 meters in 3 seconds. The average speed can be calculated this:
S = D/t
Where; d = 50m, t = 3s
S = 50/3
S = 16.6666666
S = 16.67m/s
