Jim began a 141-mile bicycle trip to build up stamina for a triathlete competition. Unfortunately, his bicycle chain broke, so he finished the trip walking. The whole trip took 5 hours. If Jim walks at a rate of 3 miles per hour and rides at 31 miles per hour, find the amount of time he spent on the bicycle.
