Given:
The distance is d1 = 3.5 km in time t1 = 30 minutes = 0.5 h
The distance is d2 = 2.5 km in time t2 = 30 minutes = 0.5 h
To find the average speed of the runner.
Explanation:
The average speed can be calculated as
[tex]\begin{gathered} v_{av}=\frac{total\text{ distance}}{total\text{ time}} \\ =\frac{d1+d2}{t1+t2} \\ =\frac{3.5\text{ +2.5}}{0.5+0.5} \\ =6\text{ km/h} \end{gathered}[/tex]Final Answer: The average speed is 6 km/h.
