Algebra.Com's Answer #509224 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! two friends live 2.1 mi apart along the same road. \n" ); document.write( " If they walk toward each other at rates that diff by 1/2 mph and meet 36mins later \n" ); document.write( " how fast was each person walking? \n" ); document.write( ": \n" ); document.write( "Let w = walking speed of the slower guy \n" ); document.write( "then \n" ); document.write( "(w+.5) = walking speed of the faster guy \n" ); document.write( ": \n" ); document.write( "Since we a working in mph, change 36 min: 36/60 = .6 hrs \n" ); document.write( ": \n" ); document.write( "When they meet their total distances will equal 2.1 mi \n" ); document.write( ": \n" ); document.write( "Write a distance equation, dist = speed * time \n" ); document.write( ".6w + .6(w+.5) = 2.1 \n" ); document.write( ".6w + .6w + .3 = 2.1 \n" ); document.write( "1.2w = 2.1 - .3 \n" ); document.write( "w = 1.8/1.2 \n" ); document.write( "w = 1.5 mph for the slow guy \n" ); document.write( "and \n" ); document.write( "2.0 mph for the speedster \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Confirm this solution by finding the actual dist each walked \n" ); document.write( "1.5*.6 = .9 \n" ); document.write( "2.0*.6 = 1.2 \n" ); document.write( "------------- \n" ); document.write( "total: 2.1 \n" ); document.write( " |
