Question

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

Answer 1

Answer:

5.6 miles

Step-by-step explanation:

$\frac{7}{80} =\frac{x}{64}$   Set up the proportion

$7(64)=x(80)$  Cross multiply

$448=80x$     Simplify

$\frac{448}{80}=\frac{80x}{80}$    Divide both sides by 80

$5.6=x$
