A motorboat can maintain a constant speed of 50 miles per hour relative to the water. The boat makes a trip upstream to a certain point in 27 minutes; the return trip takes 23 mins. What is the speed of the current?
\n" ); document.write( "***
\n" ); document.write( "let c=speed of current
\n" ); document.write( "50+c=speed of boat downstream
\n" ); document.write( "50-c=speed of boat upstream
\n" ); document.write( "distance=travel time*speed (equal for upstream and downstream)
\n" ); document.write( "23(50+c)=27(50-c)
\n" ); document.write( "1150+23c=1350-27c
\n" ); document.write( "50c=200
\n" ); document.write( "c=4
\n" ); document.write( "speed of current=4 mph
\n" ); document.write( "
