Chris drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 6 hours. When Chris drove home, there was no traffic and the trip only took 4 hours. If his average rate was 22 miles per hour faster on the trip home, how far away does Chris live from the mountains?

    Keisha drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 8 hours. When Keisha drove home, there was no traffic and the trip only took 6 hours. If her average rate was 16 miles per hour faster on the trip home, how far away does Keisha live from the mountains? way up distance from home = x speed = y time =8 hours d=rt x=8y x-8y=0...............(1) return distance =x speed = y+16 time = 6 hours x=6(y+16) x=6y+96 x-6y=96...............(2) x -8 y = 0 .............1

    x -6 y = 96 .............2 Eliminate y multiply (1)by 6 Multiply (2) by 8 6 x -48 y = 0 8 x -48 y = 768 Add the two equations 14 x = 768 / 14 x = 55 plug value of x in (1) 1 x -8 y = 0 55 -8 y = 0 -8 y = 0 -55 -8 y = -55 y = 7 x= 55 the distance from home
