amy is training for a triathlon, a timed race that combines swimming, biking, and running. because her pool sessions are helping her swim more quickly, amy plans to reduce by 1 hour per week the time she spends training on the bike and increase by 1 hour the time she spends in the swimming pool; however, her husband says that she should stop doing any biking and running and spend all 20 hours per week in the pool.
