Hi

Heather runs 7 miles in 80 minutes. 

At the same rate, how many miles would she run in 64 minutes?

Let x represent miles would she run in 64 minutes?

Question Sets Up the Proportion

 +7%2F80+=+x%2F64+     |Cross Multiplying to solve for x

      x = 7*64/80

      x = 5.6mi

  5.6/64 = .0875 = 7/80
