Question

Janet has already run 12 miles on her own, and she expects to run 1 mile during each track practice. How many track practices would it take for Janet to run 38 miles?

Answer 1

26 Track practices

Step-by-step explanation:

Janet has already run 12 miles on her own.

For each track practice, she expects to run 1 mile.

Let the number of track practices = x

Therefore, the total miles run after x track practices

`=12+1x`

If her total miles run = 38 miles, then:

`\begin{gathered} 12+1x=38 \\ x=38-12 \\ x=26 \end{gathered}`

It would take her 26 track practices to run 38 miles.
