Algebra.Com's Answer #406576 by DrBeeee(684) ![]() You can put this solution on YOUR website! Firstly, I have a question,\"How do you convert 4min and 48sec to get 28sec? Or how do you get 3hr and 50min = 590sec? \n" ); document.write( "Let's do it right. \n" ); document.write( "There are 60sec/min, so \n" ); document.write( "(1) 4 min = 4*60 sec or \n" ); document.write( "(2) 4 min = 240 sec \n" ); document.write( "Now add 48 sec and get \n" ); document.write( "(3) time to earn $1000 is 288 seconds \n" ); document.write( "This is an earning rate of \n" ); document.write( "(4) pay rate = 1000/288 $/sec \n" ); document.write( "This rate, by the way is $12,500/hr. \n" ); document.write( "Now you want to find out how much is earn for 3hr and 50min. Let's convert this to seconds. \n" ); document.write( "There are 60min/hr, so \n" ); document.write( "(5) 3 hr = 3*60 min or \n" ); document.write( "(6) 3 hr = 180 min \n" ); document.write( "Now add 50 minutes and get \n" ); document.write( "(7) The total time worked is 230 minutes. However our rate is $ per sec, so we must covert 230 minutes to seconds. \n" ); document.write( "(8) Work time is 230min*60sec/min = 230*60 = 13,800 sec \n" ); document.write( "Then the total earnings are \n" ); document.write( "(9) Earnings = 1000/288*13800 \n" ); document.write( "(10) Earnings = $47,916.67 \n" ); document.write( "We could also find the earning for 3 and 5/6 of an hr using \n" ); document.write( "(11) Earnings = 12,500*23/6 = $48,916.67 \n" ); document.write( "Question: Who dreamed up this rediculous problem? \n" ); document.write( " |
