John runs a marathon 26.2 mi in 4 hours determine how many miles he runs per hour if the proportional relationship is represented by 4y = 26.2 x

Answer 1

To determine how many miles John runs per hour, we need to rearrange the given equation to solve for y, which represents the number of miles he runs per hour.

4y = 26.2x

Dividing both sides of the equation by 4, we get:

y = 6.55x

In this equation, x represents the number of hours.

Since John runs the marathon in 4 hours, we can substitute 4 for x:

y = 6.55(4)
y = 26.2

Therefore, John runs 26.2 miles per hour when he completes the marathon in 4 hours.
