Some questions on the GMAT involve metric units of measure, whereas others involve English units of measure. However, except for units of time, if a question requires conversion from one unit of measure to another, the relationship between those units will be given.

Example: A train travels at a constant rate of 25 meters per second. How many kilometers does it travel in 5 minutes? image

Solution: In 1 minute the train travels image meters, so in 5 minutes it travels 7,500 meters. Since image meters, it follows that 7,500 meters equals image, or 7.5 kilometers.
