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( " |
