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.
