Alice had borrowed a bicycle from her friend, Bob, and wanted to return it. She rode the bicycle from her house to Bob's house at 7 miles per hour. She jogged back home from Bob's house to her house at a pace of 5 miles per hour. It took Alice 36 minutes (i.e., 3/5 hour) total travel time to make her round trip.
(a) How long (in minutes) did each leg of Alice’s trip take? That is, how long did it take Alice to travel to Bob’s house? How long did it take Alice to travel home from Bob’s house?
(b) What is the distance between Alice's and Bob's houses?
