Geri ran in a marathon race. it took her 3 hours and 28 minutes to run 26 miles. how many minutes did it take her to run 1 mile if she ran at the same rate for the whole race ?
(1 hour = 60 minutes)

3 hours and 28 minutes=3 hours(60 minutes/1 hour)+28 minutes=
180 minutes+28 minutes=208 minutes.

ratio =number of miles / time
ratio =26 miles / 208 minutes=0.125 miles/1 minute

ratio=number of miles / time  ⇒ Time=number of miles/ ratio

Data:
Ratio =0.125 miles/1 minute
number of miles=1 mile

Time=1 mile / (0.125 miles/1 minute)=8 minutes.
