Answer:
2,500m/h
Explanation:
Average speed is calculated as total speed traveled divide by total time taken:
[tex]s_{avg}=\frac{d_{total}}{t_{total}}[/tex]
Given total distance as 7250m and total time as [tex]2009-1715hrs= 2hrs \ 54min=2.9hrs[/tex], speed is calculated as :
[tex]s_{avg}=\frac{d_{total}}{t_{total}}\\\\s_{avg}=\frac{7250m}{2.9hrs}\\\\=2500\ m/h[/tex]
Hence, Joshua's speed is 2,500m/h
