Don Williams uses his small motorboat to go 4 miles upstream to his favorite fishing spot. Against the current, the trip takes 1/3 hour. With the current the trip takes 1/6 hour.
\n" ); document.write( "---------------------
\n" ); document.write( "With the current DATA:
\n" ); document.write( "dist = 4 mi ; time = 1/6 hr ; rate = 4/(1/6) = 24 mph
\n" ); document.write( "-----------------
\n" ); document.write( "Against the current DATA:
\n" ); document.write( "dist = 4 mi ; time = 1/3 hr ; rate = 4/(1/3) = 12 mph
\n" ); document.write( "--------------
\n" ); document.write( "Find the speed of the current:
\n" ); document.write( "b + c = 24 mph
\n" ); document.write( "b - c = 12 mph
\n" ); document.write( "-----------------
\n" ); document.write( "2c = 12 mph
\n" ); document.write( "Current = 6 mph
