GMAT Math Distance-Rate-Time Overview
Some GMAT questions will ask you to figure out a distance when given the time and rate something travels at. You will need to plug the data given into the Distance Formula.
Distance = Rate x Time
Unfortunately, the GMAT rarely tests these concepts in such a straightforward manner. Instead, it includes pesky problems in which you must apply your knowledge of the rate equation to some fairly contrived situations, with multiple vehicles that are moving at different speeds (and for different amounts of time).
The underlying concept is simple, as illustrated by the following example:
If Maggie drives at an average speed of 80 miles per hour, how long will it take him to travel 720 miles?
Since,
Distance = Rate x Time
Time = Distance/Rate
= (720 miles/80miles per hour)
= 9 hours
