Jessica is walking home from a friend's house. After two minutes she is 1.2 miles from home. Seventeen minutes after leaving, she is 0.7 miles from home. What is her rate in miles per hour?
---------------
She moved 0.5 miles in 15 minutes.
= 0.5 miles in 0.25 hours
-----
To find mi/hr divide the miles by the hours.
0.5 miles/0.25 hours = 2 mi/hr

Let rate be S
Then we get the following DISTANCE equation: _______
2S + 72 = 17S + 42 ------- Multiplying by LCD, 60
2S � 17S = 42 � 72
� 15S = - 30
S, or speed =
