Rate questions, so far as I can remember, have been a staple of almost every standardized test I’ve ever taken. I recall seeing them on proficiency tests in grade school. They showed up on the SAT. They were on the GRE. And, rest assured, dear reader, you will see them on the GMAT. What’s peculiar is that despite the apparent ubiquity of these problems, I never really learned how to do them in school. This is true for many of my students as well, as they come into my class thinking that they’re just not very good at these kinds of questions, when, in actuality, they’ve just never developed a proper approach. This is doubly true of work problems, which are just a kind of rate problem.

(This is one of a series of GMAT tips that we offer on our blog.)
Rate problems on the GMAT can take a variety of forms, and can often be time consuming for test takers. They also offer a challenge for students who rely on memorization, as it can be trickier than expected to apply the correct relationship between the rate, distance, and time variables.
For a foolproof way to remember the proper relationship, keep in mind that you will almost certainly encounter a rate on your drive to the test center: Miles per hour. Because the word “per” indicates division, you can remember that the rate is the distance (miles) divided by the time (hour). Accordingly, R = D/T.
