I think this problem belongs on this thread. A few of us in my class are having difficulty with this problem:
Trisha ran to the park and then walked home. It took her 1/2 hour to get to the park and 1 hour and 20 minutes to get home. If she runs 5 miles an hour faster than she walks, how far does she live from the park?
I keep coming up with two variables when I create my equation. Here's what I have:
d = round trip from home to park
d/2 = distance from her home to park (answer)
rate walking = r
rate running = r+5
time = 80 minutes walking
time = 30 minutes running
Equation:
d = 80r + 30(r+5)
Now I'm stuck with two variables and can't figure out how to continue. Thanks for your help.
