<PRE><B>Question 633944</B>
On Saturday, Earl rode his bike for 2 hours longer than Ted. Earl traveled 135 km and Ted traveled 81km. If they both averaged the same rate of speed, how long did earl ride?
---------
Earl DATA:
distance = 135 km ; time = x+2 hrs ; rate = d/t = 135/(x+2) kph
-----------------
Ted DATA:
distance = 81 km ; time = x hrs ; rate = d/t = 81/x kph
----
Equation:
time = time
135/(x+2) = 81/x
----
135x = 81x + 162
---
54x = 162
x = 3 hrs (Ted riding time)
