A boat travels 15 miles upstream and returns. \n" ); document.write( " If the boat travels 14 mph in still water, find the speed of the current if the total trip takes 2 hours and 20 minutes. \n" ); document.write( ": \n" ); document.write( "Let c = the speed of the current \n" ); document.write( "then \n" ); document.write( "(14+c) = effective speed downstream \n" ); document.write( "and \n" ); document.write( "(14-c) = effective speed upstream \n" ); document.write( ": \n" ); document.write( "Change 2 hrs 20 min to \n" ); document.write( ": \n" ); document.write( "Write a time equation: time = dist/speed \n" ); document.write( ": \n" ); document.write( "Upstream time + downstream time = 2 hrs 20 min \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
