                                                             WORD PROBLEMS--RATES #1-KEY

 


Directions:  Find the rate in each problem below.  There are several ways to solve rate problems.  The simplest

 strategy is to simply divide the data.  The key is to divide the data in the correct order.  If the question asks

you to find the miles/hour, then you should find the quotient of the miles divided by the hours, not the hours

divided by the miles.
