The question is incomplete, the complete complete question will be:
Lucy drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 9 hours. When Lucy drove home, there was no traffic and the trip only took 4 hours. If her average rate was 40 miles per hour faster on the trip home, how far away does Lucy live from the mountains?
Lucy live at a distance of 288 miles from the mountains.
Step-by-step explanation:
DATA:
To the mts DATA:
Time = 9 hrs
Rate = r mph
Distance = 9r miles
From the mts DATA:
time = 4 hrs
rate = r+40 mph
distance = 4(r+40) miles
SOLUTION
Distance to = Distance from
9r = 4r + 160
5r = 160
r = 32 mph
RESULT:
Distance = 9r = 9*32 = 288 miles
