Algebra.Com's Answer #840715 by greenestamps(13203)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "The solutions in the three responses you have found are very similar, essentially using x and (2/3)x for the speeds of the two cyclists. \n" ); document.write( "Here is a different approach. \n" ); document.write( "The rates of the two cyclists are in the ratio 2:3, so the distances traveled by the two cyclists are in the ratio 2:3. Using a standard method for setting up the problem for solving using that ratio.... \n" ); document.write( "Let 2x = distance traveled by the slower cyclist \n" ); document.write( "Let 3x = distance traveled by the faster cyclist \n" ); document.write( "The total distance was 25 miles: \n" ); document.write( "2x+3x=25 \n" ); document.write( "5x=25 \n" ); document.write( "x=5 \n" ); document.write( "The distances traveled by the two cyclists were 2x=10 and 3x=15 miles. \n" ); document.write( "Since the two cyclists met after 2 hours, their speeds were 10/2 = 5mph and 15/2 = 7.5mph \n" ); document.write( "ANSWER: 5mph and 7.5mph \n" ); document.write( " \n" ); document.write( " |
