Answer:
3000
Step-by-step explanation:
a decrease in the ratio 5:3 implies that:
new quantity :old quantity :5:3
let new quantity be x.
x:1800=5:3
x/1800=5/3
3x=9000
x=9000/3
x=3000

Answer:
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
