document.write( "2 cars start from points 92 miles apart and travel directly towards each other. one car starts at 11am and travels slower and the other starts at 11:15am and goes faster to make up for lost time. they meet at 12pm find the average speed of each car, if the slower car travels 6 mph slower than the faster one. \n" );

Algebra.Com's Answer #446546 by mananth(16946)![]() ![]() You can put this solution on YOUR website! let the speed of slower car be x \n" ); document.write( "the speed of car II = x+6\r \n" ); document.write( "\n" ); document.write( "They meet after 1 hour after car I starts\r \n" ); document.write( "\n" ); document.write( "distance by car I = x \n" ); document.write( "distance by car II = (x+6)*3/4........... ( speed * time)\r \n" ); document.write( "\n" ); document.write( "x+3/4(x+6)=92\r \n" ); document.write( "\n" ); document.write( "multiply by 4 \n" ); document.write( "4x+3(x+6)=368\r \n" ); document.write( "\n" ); document.write( "4x+3x+18=350 \n" ); document.write( "7x=350 \n" ); document.write( "x=50 \r \n" ); document.write( "\n" ); document.write( "50 & 56mph \n" ); document.write( " |
