<PRE><B>Question 1055078</B>
The speed of a stream is 5 mph. A boat travels 2 miles upstream in the same time it takes to travel 12 miles downstream. What is the speed of the boat in still&amp;#8203; water? 
-------------------
Upstream DATA:
distance = 2 miles ; rate = b-5 mph ; time = d/r = 2/(b-5) hrs
---------------
Downstream DATA:
dist = 12 miles ; rate = b+5 mph ; time = 12/(b+5) hrs
----------------
Equation:
2/(b-5) = 12/(b+5)
-----------
2b + 10 = 12b - 60
------
10b = 70
boat speed = 7 mph (speed in still water)
------------

Stan H.
