anonymous · Answer

I have a few of these questions I have to do:
Boris drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 8 hours. When Boris drove home, there was no traffic and the trip only took 5 hours. If his average rate was 21 miles per hour faster on the trip home, how far away does Boris live from the mountains?
