Question 908927: An experienced bricklayer can work twice as fast as an apprentice bricklayer. After they worked together on a job for 4 h, the experienced bricklayer quit. The apprentice required 12 more hours to finish the job. How long would it take the experienced bricklayer, working alone, to do the job? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! e= experienced
a= apprentice
e=a/2
4/e+4/a+12/a=1
4/(a/2)+16/a=1
8/a+16/a=1
24/a=1
a=24 apprentice
e=12 experienced
