                    rate          time         distance

morotcyclist       d/(1&1/2)      1&1/2        d

cyclist            d/2            2            d


Compare their rates.
Motorcycle
Cyclist

At what time t was .....
                 rate           time        distance   Distance from B
mototcycl        (2/3)d          t          (2/3)dt    d-(2/3)dt
cycl             (1/2)d          t          (1/2)dt    d-((1/2)dt

When was cylcist twice as far from B as was motorcyclist?


That equation uses two unknown variables, d and t; and one of them will be found as factor on both members.
