denis-greek [22]

Answer:

6.25 m/s

Explanation:

Given parameters

Initial mark = 65

Final mark = 15

time taken = 8s

Unknown:

Velocity of the runner = ?

Solution:

Velocity is the displacement divided by time;

Velocity = $\frac{displacement}{time}$

Displacement = Initial mark - final mark = 65 - 15 = 50m

Now, insert the parameters and solve;

Velocity = $\frac{50}{8}$ = 6.25m/s
