Odometer starting read = 20823
Ending = 21371
So total distance traveled is:
[tex]\begin{gathered} \text{ Distance=21371-20823} \\ =548 \end{gathered}[/tex]
Time taken during traveling is:
[tex]10.5\text{ hours}[/tex]
So the average speed is:
[tex]\text{ Sp}eed\text{ = }\frac{\text{ Distance}}{\text{ Time}}[/tex][tex]\begin{gathered} \text{ Sp}eed=\frac{\text{ Distance}}{\text{ Time}} \\ \text{Speed}=\frac{548}{10.5} \\ \text{ Spe}ed=52.19 \end{gathered}[/tex]
So the average speed is 52.19 miles/hour
