I'm having a fairly hard time creating an equation from the information given to complete this problem. Here it is.
"On a vacation, Elwyn averaged 50 mph traveling from Denver to Minneapolis. Returning by a different route that covered the same number of miles, he averaged 55 mph. What is the distance between the two cities if his total traveling time was 32 hr."
So we have two rates & times: 50 mph at x hours and 55 mph at (32-x) hours.
anyone know where to start?
