Let = distance in miles the west - east cyclist
travels until meeting car
-----------------------------------------
= distance in miles east - west car
travels until meeting cyclist
-----------------------------------------
Let = the speed of the cyclist in mi/hr
= the speed of the car in mi/hr
------------------------------------------
Equation for W - E cyclist
(1)
-------------------------
Equation for E - W car:
(2)
-----------------------------------
Substitute (1) into (2)

and

-----------------------
The bike's ave. rate is 13.8 mi/hr
The car's ave. rate is 46.2 mi/hr
