Question

Isabel drove 864 miles in 12 hours.
At the same rate, how many miles would she drive in 7 hours?

Answer 1

Answer:

504 miles

Step-by-step explanation:

Make a proportion

$\frac{864}{12}$ = $\frac{x}{7}$

7/12 is 0.5833, so multiply 864 by that to find the number of miles

864(0.5833) = 504

Answer 2

Isabel drove 504 miles in 7 hours
