Jim began a 164-mile bicycle trip to build up stamina for a triathlon competition. Unfortunately, his bicycle chain broke, so he finished the trip walking. The whole triptook 6 hours. If Jim walks at a rate of 4 miles per hour and rides at 44 miles per hour, find the amount of time he spent on the bicycle

x = bike time      6-x = walk time

 

44x    +   4 (6-x)    = 164         solve for x          (He bikes at 44 mph!   Wow! cheeky )
