John runs a marathon (26.2 miles) in 4 hours. Determine how many mile he runs per hour if the proportional relationship is represented by 4y = 26.2x
0.15 mph
7 mph
104.8 mph
6.55 mph
To find how many miles John runs per hour, we need to solve for x in the equation 4y = 26.2x.
Divide both sides of the equation by 26.2 to isolate x:
x = (4y) / 26.2
Since we are looking for how many miles he runs per hour, we want to find the value of x when y = 1 (since y represents the number of hours).
x = (4(1)) / 26.2
x = 4 / 26.2
Now we calculate the value of x:
x = 0.152
Therefore, John runs approximately 0.152 miles per hour.
But since we are asked to round to the nearest hundredths place, the answer is approximately 0.15 mph. So the correct answer is 0.15 mph.
