A man who can row in still water at 5 mph heads directly across a river flowing at 6 mph.
\n" ); document.write( "At what angle to the line on which he is heading does he drift downstream (nearest degree)?
\n" ); document.write( "-----
\n" ); document.write( "Draw the picture:
\n" ); document.write( "Let his time across the river be x hrs.
\n" ); document.write( "-----
\n" ); document.write( "You have a right triangle with base = 6x
\n" ); document.write( "height (perpendicular distance across river) = 5x
\n" ); document.write( "----
\n" ); document.write( "Note: Not sure what angle you want.
\n" ); document.write( "Angle he travels measured from his starting point is theta
\n" ); document.write( "and tan(theta) = 5x/6x = 5/6
\n" ); document.write( "Theta = arctan(5/6) = 39.81 degrees.
