Question 1131032
 A boat can travel 24 miles downstream in 2 hrs. The return trip takes 3 hrs. Find the speed of the boat in still water.
-------
Downstream rate = 24 miles/2 hrs = 12 mph
Upstream rate = 24 miles/3 hrs = 8 mph
-------------------------
Let" "b" be the speed of the boat in still water; Let "c" be the current rate.
-----
Equations:
b + c = 12 mph
b - c = 8 mph
----------
2b = 20 mph
b = 10 mph (boat speed in still water)
