Question

Raina runs 7 miles in 60 minutes. At the same rate, how many miles would she run in 24 minutes?

Answer 1

Raina runs 7 miles in 60 minutes. So we have the proportion of \[\frac{7 \text{ miles }}{60 \text{ minutes }}\]

Answer 2

Now using proprtions we determine how much Raina will run in 24 minutes
\[\frac{7 \text{ miles }}{60 \text{ minutes }}=\frac{x\text{ miles }}{24 \text{ minutes }}\]

Answer 3

Now we cross multiply and get
\[7*24=60x\]
\[168=60x\]
\[\frac{168}{60}=x\]
\[x=2.8\]
