Jim began a 153-mile bicycle trip to build up stamina for a triathlete competition. Unfortunately, his bicycle chair broke, so he finished the trip walking. The whole trip took 6 hours. If Jim walks at a rate of 3 mph and rides at 33 mph, find the amount of time he spent on the bicycle.

Question

anonymous · Answer

we have the distance and the velocity split ups

anonymous · Answer

say rode for x miles
then he walked for 153-x miles

anonymous · Answer

total time taken would be (x/33)+((153-x)/3) that is given to be 6 hours
so find x
then use it to find the time taken

anonymous · Answer

so the equation would be x/33+153-x/33=6?  and I just solve for x?

anonymous · Answer

yep solving for x gives you the distance he rode
then time can be calculated from t=distance/velocity=x/33
