Question

Miguel drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 10 hours. When Miguel drove home, there was no traffic and the trip only took 7 hours. If his average rate was 18 miles per hour faster on the trip home, how far away does Miguel live from the mountains?

Answer 1

There were about three hours of extra traffic. Miguel traveled about 126 miles up to the mountains, so your answer is:  126 miles
