Question

Isabel drove 864 miles in 12 hours.

At the same rate, how many miles would she drive in 7 hours?

Answer 1

Isabel drove 504 miles in 7 hours

Answer 2

504 miles

Explanation:

Make a proportion

`(864)/(12)` =
`(x)/(7)`

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

864(0.5833) = 504
