You can put this solution on YOUR website! Suzi drove home at 60 mph, but her brother Jim, who left at the same time, could drive at only 48 mph. When Suzi arrived, Jim still had 60 miles to go. How far did Suzi drive?
:
The difference in the distance they traveled is 60 miles, so if you subtract the two distances=60.
:
We have to go about this indirectly, by finding out how long they traveled, then find out how far Suzi drove. The distance formula is:  , where d=distance, r=rate, and t=time. They both drove the same amount of time:t.
:
The distance Suzi drove is: 60t
The distance Jim droze is: 48t
The difference between them is: 60
:
The equation is:
60t-48t=60
12t=60
12t/12=60/12
t=5 hr
:
The distance Suzi drove is: 60t=60(5)=300 miles.
Happy Calculating!!!
