Algebra.Com's Answer #481636 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! Let a = speed of faster walker \n" ); document.write( "Let b = speed of the slower \n" ); document.write( ": \n" ); document.write( "6 min to .1 hrs \n" ); document.write( ": \n" ); document.write( "Write an distance equation for each statement: \n" ); document.write( "dist = time * speed\r \n" ); document.write( "\n" ); document.write( "Two men starting at a point on a circular 1-mile race track walk in opposite directions with uniform speeds and meet in 6 minutes, \n" ); document.write( ".1(a + b] = 1 \n" ); document.write( "multiply both sides by 10 \n" ); document.write( "a + b = 10 \n" ); document.write( ": \n" ); document.write( " but if they walk in the same direction, it requires one hr for the faster walker to gain a lap.
