Cheryl is training for a long bicycle ride. Jim will drive Cheryl back and her bicycle 60 miles from town, drop them off, and then drive back to town. Cheryl then will ride her bicycle back to town. On the way back to town, Jim will travel at 50 miles per hour and Cheryl will travel at 15 miles per hour. Cheryl plans on making two 15 minute rest stops. If Jim and Cheryl start back at the same time, how long, in hours and minutes, after Jim arrives in town Cheryl will arrive in town?
Jim takes 60/50 hrs = 72 minutes to drive back
Cheryl takes 4 hours = 240 minutes to ride and 30 minutes to rest = 270 min. in all.
270-72 = 198 min, or 3 hours and 18 min.
Hope Jim had a book...
