Question 1191967: Suppose a family drives an average rate of 60mi/h on the way to visit relatives and then at an average rate of 40mi/h on the way back. The return trip takes 1 h longer than the trip there.
a. Let d be the distance in miles the family traveled to visit their relatives. How many hours did they take to drive there?
b. In terms of d, how many hours did it take to make the return trip?
c. Write and solve an equation to determine the distance the family traveled to see their relatives. What was the average rate for the entire trip?
