Question

Pierre runs the same around a track each day 4 days a week.He runs a total of 12 miles each week.It takes 8 laps of the track to equal a mile.Which equation could you use to find how many laps Pierre runs each day?

Answer 1

Answer:

$4l=8\cdot 12$

Step-by-step explanation:

Let l represent number of miles ran by Pierre each day.

We have been given that Pierre runs the same around a track each day 4 days a week. So number of laps ran is 4 days would be $4l$.

We are also told that he runs a total of 12 miles each week and it takes 8 laps of the track to equal a mile. So number of laps in 12 miles would be 8 times 12.

Now, we will equate total laps ran in 4 days by 8 times 12 as:

$4l=8\cdot 12$

Therefore, we can use the equation $4l=8\cdot 12$  to find how many laps Pierre runs each day.

Let us solve for l as:

$\frac{4l}{4}=\frac{8\cdot 12}{4}$

$l=2\cdot 12$

$l=24$

Therefore, Pierre runs 24 laps each day.
