Rita sprints 40m to the right in 5.5s.
What was her average velocity in m/s?

Average velocity is 7.27m/s.

Explanation:

Given the following parameters;

Distance (d) = 40m

Time (t) = 5.5secs

Velocity =?

Velocity can be defined as the rate of change in displacement (distance) with time.

Mathematically, velocity is given by the equation;

Substituting into the above equation;

V = 7.27m/s

Hence, Rita's average velocity is 7.27m/s.
