Question

Keiko runs 7 miles in 80 minutes. At the same rate, how many miles would she run in 64 minutes?

Answer 1

Keiko would run 5.6 miles in 64 minutes at the same rate

Explanation:

we can set up a proportion in order to solve this equation from this problem to do that we first need to solve this proportion we need to cross-multiply and then divide:

7 miles * 64 minutes = 80 minutes * x miles

448 miles = 80x

Divide both sides by 80:

448 miles / 80 = x miles

5.6 miles = x miles
