The GMAT Work Rate Problems module is one of the GMAT Quant topics from my GMAT Study Guide. This module includes recommended GMAT study materials and GMAT practice questions from the Official Guide and Veritas Prep GMAT books. It covers concepts and approaches that are helpful for solving work rate problems, including combining rates and converting between rate and time.

If you want to work on both work rate and distance rate problems at the same time, please visit the GMAT Rate Problems module.

If you are having any trouble interpreting and/or solving the GMAT practice questions for this module, you may also want to review the GMAT Word Problems module.
