John runs 3miles in 22 minutes. At the same rate, how many miles would he run in 55 minutes?

OpenStudy (firejay5):

It should be 7.5 miles. Set it up into a proportion. 3mi/Xminutes = 22mi/55minutes

OpenStudy (firejay5):

22x = 165 and divide 22 from both sides to get 7.5 miles Rounding would be 8 miles.
