Olivia and Addison both bike 3 miles per week in week 120.

Olivia and Addison both bike 120 miles per week in week 3.

Olivia bikes 120 miles and Addison bikes 3 miles.

Answer 1

The point of intersection (3, 120) on the graph indicates that both Olivia and Addison have the same biking distance at that specific point in time. In the context of the problem, this means:

Both Olivia and Addison bike 120 miles in the third week.

Thus, the correct interpretation is: Olivia and Addison both bike 120 miles in week 3.
