Problem page isabel runs 7 miles in 50 minutes. at the same rate, how many miles would she run in 75 minutes?

if isabel runs 7 miles in 50 minutes, then you know she runs 7/50 miles in one minute, right? So multiply that by the number of minutes she did run, and you can find the distance:

7
x 75 =
50

525

50

If you plug that fraction into your calculator, you get 10.5, so 10 and a half miles.
