Question

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

Responses

6.55 mph

104.8 mph

0.15 mph

7 mph

Answer 1

the bot is correct its 6.55

Answer 2

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

4y = 26.2x

To find y, we divide both sides of the equation by 4:

y = 26.2x/4

Since x represents the number of hours, we can replace x with 1 (as John runs the marathon in 4 hours):

y = 26.2(1)/4

y = 26.2/4

y = 6.55

So John runs 6.55 miles per hour.

Therefore, the correct response is:

6.55 mph.

Answer 3

Thank you for confirming! Yes, the correct answer is indeed 6.55 mph.
