Question 914576
___________________rate__________time__________distance
CAR________________48_____________t_____________d
CYCLER_____________12____________t+3____________d



Setting the data table correctly, as shown above, is a big help in solving for problem.  Filled as it is, use the basic rule for uniform travel rates, RT=D; but for the problem, t is chosen as the time for the car to overtake the cyclist.  Note how the cyclist travels for 3 hours more than the car.  Notice also how the car traveling at the higher rate moved for less time than the slower cyclist who left three hours earlier.
