Tom is going for a run. he runs for 12.5 miles at a speed of 5 miles per hour. for how many hours does he run? 2.5 hours, right?

Hello!

To find how many hours Tom ran, we need to know that to find miles per hour, you need to divide miles over hours (miles per hour = miles/hours).

Given that he runs 5 miles per hour and he ran a total of 12.5 miles, we can find how much hours he ran.

5 mph = 12.5 miles / x hours (multiply both sides by x hours)

5x mph = 12.5 miles (divide both sides by 5 miles)

x = 2.5 hours

Therefore, you are correct, Tom ran 2.5 hours.

the answer is b.
