Given that a group of hikers walked miles along a hiking trail. Another group of hikers walked that distance with the first group before turning off onto another trail. Now we need to fnd about how many miles did the two groups of hikers walk with each other.
I like to solve these by graphing, so if you graph both of these functions (as shown in the picture below), you look for the intersection between the two graphs, which in this case is (-2,6).
