You’ve ridden in a car enough times to know it travels a specific rate, such as miles per hour, to reach its destination. You’ve also seen the speed limit signs designating the maximum rate allowed for a particular stretch of road. If you look up directions to a place you want to go, then you’ll find the distance between your current location and your destination and the time it will take you to get there. These calculations are based on the simple formulas for distance, rate, and time.
The formulas for rate and time are just variations of the distance formula. In the distance formula, you use rate (R) and time (T) to find distance (D). To find rate, you simply need to use time and distance; to find time, you use rate and distance. If you can remember the distance formula, then you can easily find the rate formula and time formula:
