A runner whose initial speed is 29km/h increases her speed to 31km/h in order to win a race. If the runner takes 5.0s to complete this increase in her speed, what is her accelration
Average velocity = \(a\) =\(\frac{{x}_{f} - {x}_{i}} {{t}_{f} - {t}_{i}}\)
Where:
\({x}_{f}\)= Final position
\({x}_{i}\)= Initial position
\({t}_{f}\)= Final time
\({t}_{i}\)= Initial time
Acceleration = \(\frac{Velocity}{Time}\)

That is what I can do for sure, but I am not able to solve that right now. Maybe you can figure the answer out yourself with these formulas?
