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
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.
