Algebra.Com's Answer #396663 by htmentor(1343) You can put this solution on YOUR website! I'll set the problem up and leave it to you to solve. \n" ); document.write( "Let t = the time required for Sam to do the job alone \n" ); document.write( "Then Pete takes t - 4 hrs to do the job \n" ); document.write( "Working together their combined rate is: \n" ); document.write( "1/t + 1/(t-4) = 1 job/16 hr = (1/16) jobs/hr \n" ); document.write( "Now you just need to solve for t \n" ); document.write( "I'm getting 30.1 and 34.1 hrs, to the nearest tenth \n" ); document.write( " |
