Question

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.

Answer 1

26.2 miles/ 210 mins = x miles / 1min
1 * 26.2 / 210 = .12 miles / min

Answer 2

`(Miles)/(Minute) (26.2)/(210)=(x)/(1)`

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
