<PRE><B>Question 321212</B>
linda and dave leave from the same starting point, biking in opposit directions... linda bikes at 7mph, and dave bikes at 10mph.  how long will it be until they are 22 miles apart from each other
--------
They are separating at a rate of (7+10)= 17mph
----
time = distance/rate
---
time = 22 mi/17 mph = 1.2941 hrs.
