$r= \frac{d}{2}= \frac{26}{2} \;\Rightarrow r=13\,cm \\ \\ 
V= \frac{4}{3} \pi r^3 \\ \\ 
V= \frac{4}{3} \pi \,(13)^3 \\ \\ 
V= \dfrac{4\cdot 2197}{3} \pi \\ \\ 
V= \frac{8788}{3} \pi\approx 9202,77\,cm^3$

Avg. Speed = 45.29 miles per hour

Hence the average rate of speed for the trip was 45.29 miles per hour.
