A runner completed a 26.2 mile marathon in 210 minutes. Estimate the unit rate, in miles per minute. Round your answer to the nearest hundredth of a mile.
1) Cross multiply. (26.2 = 210x) 2) Divide 210 from each side. (26.2/210 = .1247619048 , 210x/210 = x) 3) Round to the nearest 100th. (.12) 4) X=.12 5) .12 miles ran per minute
