Rate Time Distance problems?

You start with the basic distance equation, Distance= Rate * Time. I would make x stand for the time the second ship travels, by the way, just because that's the value I'm looking for. Personal preference. That means that D(Ship 1) = 17(x + 2). D (Ship 2) = 22x. When Ship 2 overtakes Ship1, the distances will be the same, right? Make the two expressions equal, and solve for x. You can also solve it by using the two expressions you came up with and setting them equal; you just have to keep in mind that your answer will be the time of the first ship.
