Question 239884
<font face="Garamond" size="+2">


If you know the rate and the time and want to calculate the distance, use Distance = Rate X Time:  *[tex \LARGE d\ =\ rt]


If you know the distance and the rate and want to calculate the time, take *[tex \LARGE d\ =\ rt] and divide both sides by *[tex \LARGE r] to get *[tex \LARGE t\ =\ \frac{d}{r}]


If you know the distance and the time and want to calculate the rate, take *[tex \LARGE d\ =\ rt] and divide both sides by *[tex \LARGE t] to get *[tex \LARGE r\ =\ \frac{d}{t}]


So you need to first use *[tex \LARGE r\ =\ \frac{d}{t}] where *[tex \Large d\ =\ 10] to get the rate, and then use *[tex \LARGE t\ =\ \frac{d}{r}] where *[tex \Large d\ =\ 7] to get the time.


Always remember to pay attention to the units of measure.  If you just divide 10 miles by 70 minutes, you are going to get miles per minute -- NOT miles per hour.
