Manuel can drive 3 times as fast as Pedro can ride his bicycle. If it takes Pedro 4 hours longer than Manuel to travel 66 miles, how fast can Pedro ride his bicycle?
---------
Pedro DATA:
dist = 66 miles ; rate = r mph ; time = 66/r hrs
-------
Manuel DATA:
dist = 66 miles ; rate = 3r mph ; time = 66/(3r) hrs = 22/r hrs
-------------
Equation:
Pedro time - Manuel time = 4 hrs.
------
66/r - 22/r = 4
44/r = 4
r = 11 mph (Pedro rate)
3r = 33 mph (manuel rate)
-------------
