Algebra.Com's Answer #199428 by Alan3354(69443) You can put this solution on YOUR website! How do I write and solve an equation for c mows the lawn three times faster than j. How long will it take to finish the job? (do you need the acerage? It would be 2) \n" ); document.write( "------------------ \n" ); document.write( "3 times faster means it takes 1/4 as long, or j takes 4 times as long. \n" ); document.write( "c takes t hours means c does 1/t of the job per hour. \n" ); document.write( "j takes 4t hours means j does 1/4t per hour. \n" ); document.write( "Toghether, 1/t + 1/4t = 5/4t of the job per hour. \n" ); document.write( "--> 4t/5 hours together. \n" ); document.write( "------------------------ \n" ); document.write( "PS 3 times faster is 4 times as fast. If someone says it's 3 times as fast, ask how much faster is \"1 times faster?\" \n" ); document.write( "If 1 times faster is 1x the speed, why would it say \"faster?\"\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
