Question

THIS IS THE LAST QUESTION IDK HOW DO SOLVE IT :(

Lilliana is training for a marathon. She runs the same distance every day for a week. On Monday, Wednesday, and Friday, she runs 2 laps on a running trail and then runs 8 more miles. On Tuesday and Sunday, she runs 4 laps on the trail and then runs 4 more miles. On Saturday, she just runs laps. How many laps does Lilliana run on Saturday?

Answer 1

6 laps.

Explanation:

On Monday she runs 2x + 8 miles, where x miles = the length of the trail.

On Tuesday she runs 4x + 4 miles and this is the same distance as Monday, so

2x + 8 = 4x + 4

4 = 2x

x = 2 miles which is the length of the trail.

So each day she runs 4(2) + 4 = 12 miles.

So on Saturday she runs 12/ 2 = 6 laps.
