GMAT tip for Distance Rate GMAT problemsRemember those math word problems that gave you nightmares in high school algebra class? You know the ones — the problems where one train leaves Boston traveling west at a certain rate, and then another train leaves an hour later traveling on the same track at a faster rate, and then there’s some question you have to answer about distance traveled or time to impact or some other variation of distance/rate/time?

Well, I hate to break it to you, but you’re going to see those types of questions on the GMAT as well.

But I have good news for you. I’m about to make them a whole lot easier.

The Traditional Set-Up for GMAT Distance/Rate Problems

It’s useful to start by having a conceptual understanding of Distance/Rate problems on the GMAT from an algebraic perspective. As I’ve taught in other articles about GMAT Distance/Rate questions, you can use your understanding of the following formula to solve most of these question types algebraically:

Distance = Rate x Time

Distance/Rate problems on the GMAT generally come in one of three forms, and they’re effectively solved the same way. You can click on the following links to read a detailed explanation of each type:

Motion in the Same Direction (“Catch-Up”)
