Question

On his afternoon jog, Chris took 42 min to run 3 3/4 miles. How many miles can he run in 60 min?

A) 5 5/8 miles

B) 6 1/4 miles

C) 6 3/4 miles

D) 7 1/2 miles

Answer 1

Chris can run approximately 3 1/8 miles in 60 minutes.

Step-by-step explanation:

To find how many miles Chris can run in 60 minutes, we can set up a proportion based on the given information. We know that in 42 minutes, Chris runs 3 3/4 miles. So, we can set up the proportion:

42 min / 3 3/4 miles = 60 min / x miles

To solve for x, we cross multiply:

42 * x = 60 * (15/4)

Now, we can simplify and solve for x:

x = (60 * 15) / (4 * 42)

x = 25/8 = 3 1/8 miles

Therefore, Chris can run 3 1/8 miles in 60 minutes, which is closest to option B) 3 1/4 miles.
