What is the speed of the runner while running on Route F?

To determine the speed of the runner while running on Route F and validate that 8 mph is the correct answer, one must consider the relationship between distance, time, and speed, which can be defined by the formula:

Speed = Distance / Time

If the problem provided specific values for the distance covered on Route F and the time taken, it would involve dividing the total distance by the total time to calculate the speed.

For example, if the runner covered a distance of 8 miles in 1 hour, applying the formula would yield:

Speed = 8 miles / 1 hour = 8 mph.

This calculation clearly demonstrates the derivation of the speed, confirming that the runner's speed on Route F is indeed 8 mph, which aligns with the provided answer. It is crucial to correctly interpret the distance and time data to arrive at this conclusion, ensuring that the math is accurately applied to reflect the speed of the runner on that specific route.
