jim began a 92-mile bicycle trip to build up stamina for a triathlon competition. Unfortunately, his bicycle chain broke, so he finished the trip walking. The whole trip took 4 hours. If Jim walks at a rate of 3 miles per hour and rides at 35 miles per hour, find the amount of time he spent on the bicycle.

since time = distance/speed, if he rode for x miles, then
x/35 + (92-x)/3 = 4
x = 87.5 miles
now you can find the time he spent riding.
x/35 + (92-x)/3 = 4
x = 87.5 miles
now you can find the time he spent riding.
