Algebra.Com's Answer #180942 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! Matt runs 2 miles per hour faster than Adam. \n" ); document.write( " Matt runs 5 miles in the same time that Adam runs 4 miles. \n" ); document.write( " Find the speed of each of them. \n" ); document.write( ": \n" ); document.write( "let s = running speed of Adam \n" ); document.write( "then \n" ); document.write( "(s+2) = running speed of Matt \n" ); document.write( ": \n" ); document.write( "Write a time equation: Time = dist/speed \n" ); document.write( "Matts time = Adams time \n" ); document.write( " \n" ); document.write( "Cross multiply \n" ); document.write( "5s = 4(s+2) \n" ); document.write( "5s = 4s + 8 \n" ); document.write( "5s - 4s = 8 \n" ); document.write( "s = 8 mph is Adam's running speed \n" ); document.write( "and \n" ); document.write( "8 + 2 = 10 mph is Matt's \n" ); document.write( "; \n" ); document.write( ": \n" ); document.write( "Check solution \n" ); document.write( " |
