Answer
False
Work Step by Step
$$
r+8.1\approx14.76+8.1\approx22.86
.$$Therefore, the speed from Terminal A to Terminal B is approximately $22.86\text{ ft/s}$.
Converting $22.86 \text{ ft/s}$ to $\text{mi/h}$ results in
$$
\frac{22.86\text{ ft}}{\text{s}}\cdot\frac{1 \text{ mi}}{5280\text{ ft}}\cdot\frac{3600\text{ s}}{1\text{ h}}≈\frac{15.59\text{ mi}}{h}
.$$Therefore, the average speed from Terminal A to Terminal B is approximately $15.59\text{ mi/h}$. Hence, the claim that the monorail's average speed from Terminal A to Terminal B is greater than $25\text{ mi/h}$ is FALSE.
