Answer:
1 hour
Explanation:
Let's set up an equation for Tom's and Addison's distances: T(x) = 4x + 6, A(x) = 10x, where x is the amount of time since Addison started (in hours).
We solve for A(x) = T(x) and get:
10x = 4x + 6 → subtract 4x from both sides
6x = 6 → divide both sides by 6
x = 1
Therefore, it took Addison 1 hour to catch up with Tom
