The speed of a stream is 4 mph, if a boat travels 44 miles downstream in the same time that it takes to travel 22 miles, what is the speed of the boat in still water
\n" ); document.write( "----
\n" ); document.write( "Downstream DATA:
\n" ); document.write( "dist = 44 miles; rate = b+4 mph ; time = 44/(b+4) hrs.
\n" ); document.write( "-------------------
\n" ); document.write( "Upstream DATA:
\n" ); document.write( "dist = 22 miles; rate = b-4 mph ; time = 22/(b-4) hrs
\n" ); document.write( "-------------------
\n" ); document.write( "Equation:
\n" ); document.write( "time up = time down
\n" ); document.write( "44/(b+4) = 22/(b-4)
\n" ); document.write( "2/(b+4) = 1/(b-4)
\n" ); document.write( "2(b-4) = b+4
\n" ); document.write( "2b-4 = b+4
\n" ); document.write( "b = 8 mph (speed of the boat in still water)
