                   SPEED          TIME         DISTANCE

GOING               r              7             d

RETURN             r+27            4             d


7r=4%28r%2B27%29
7r=4r%2B108
3r=108
r=36

Scott drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took
7
hours. When Scott drove home, there was no traffic and the trip only took
4
hours. If his average rate was
27
miles per hour faster on the trip home, how far away does Scott live from the mountains?
Piece of advice: You don't have to determine the person's speed since that was not asked for.

You just need to set up a SPEED equation to find the distance.



I'm TIRED of seeing so many of these same "mountain" problems. Here is a list with 8 of them on here.

1001641

919699

887569

778222

838495

969368

993575

1040343

You will notice that problem # 969368 is EXACTLY like this one, with the exception that the person is YOKO instead of Scott.
