If her average rate was 18 miles per hour faster on the trip home, how far away does Teresa live from the mountains?

No you put in the answer

anonymous · Answer

ok the equation is 

18 x 10= 180
180/7=25.71

anonymous · Answer

so she lives 25.71 miles from the mountains

anonymous · Answer

$$10t=7t+18$$ 
3t=18
t=6
10t=60miles
7t=42, which is 18 mph less (or faster) than 60

anonymous · Answer

so, she lives 60 miles away.
