Bub and Bette seem to be starting from the same place but at different times and speeds.

________________rate__________time____________distance
Bubba____________r____________3%2B1%261%2F2__________d
Bubbette________42____________1%261%2F2____________d

The actual distance is not known; but both times are known, and we know RT=D as a rule for uniform rates of travel. Equate the expressions for distance d.


r%283%2B1%261%2F2%29=%2842%29%281%261%2F2%29
and solve for r.
