Changing description to THIS:
-
Jim began a 208​-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 7 hours. If Jim walks at a rate of 3 miles per hour and rides at 37 miles per​ hour, find the amount of time he spent on the bicycle.

Let b stand for time spent biking.
Time spent walking is 7-b.

Distance biking,  {{{37b}}}.
Distance walked, {{{3(7-b)}}}.


Total distance was 208 miles.
{{{highlight_green(37b+3(7-b)=208)}}}
Solve for b.
