Final answer:
Mr. Watson can run 10 miles in 60 minutes.
Step-by-step explanation:
To find how many miles Mr. Watson can run in 60 minutes, we can set up a proportion using the information given. We know that Mr. Watson ran 8 miles in 48 minutes, so the rate at which he runs is 8 miles / 48 minutes, or 1 mile per 6 minutes. We can then set up the proportion:
1 mile / 6 minutes = x miles / 60 minutes
To solve for x, we cross multiply:
6x = 1 * 60
6x = 60
x = 10
Therefore, Mr. Watson can run 10 miles in 60 minutes.
