Algebra.Com's Answer #382511 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! two cyclists, 72 miles apart, start riding toward each other at the same time, one cyclist 2 times as fast as the other, if they meet 3 hours later, what is the speed(in mi/h) of the faster cyclist \n" ); document.write( ". \n" ); document.write( "Let x = speed of faster cyclist \n" ); document.write( "then \n" ); document.write( "x/2 = speed of slower cyclist \n" ); document.write( ". \n" ); document.write( "applying the distance formula: d=rt \n" ); document.write( ". \n" ); document.write( "3x + 3x/2 = 72 \n" ); document.write( "multiplying both sides by 2: \n" ); document.write( "6x + 3x = 144 \n" ); document.write( "9x = 144 \n" ); document.write( "x = 144/9 \n" ); document.write( "x = 16 mph \n" ); document.write( " \n" ); document.write( " |
