Answer:
Explanation:
Given that,
Rachel runs 7 miles in 80 minutes.
80 minutes = 7 miles
Using unitary method
Divide 80 to both sides
1 minute = 7/80 miles
1 minute = 0.0875 miles
Multiply 64 to both sides
64 minutes = 0.0875 × 64 miles
64 minutes = 5.6 miles
So, Rachel will run 5.6 miles in 64 minutes.
