Question 279371: When all of the grocery carts escape from the supermarket,
it takes Reginald 12 minutes to round them up and bring
them back. Because Norman doesn’t make as much per
hour as Reginald, it takes Norman 18 minutes to do the
same job. How long would it take them working together
to complete the roundup? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! Well the truth of the matter is that Norman is lazy and a cheat and lacks a good work ethic.
So Reginald will be doing all the work. So it will still take Reg 12 minutes to round them up even with Norman watching!
otherwise If Norman got off his butt they could do it in half the time.
With the given rates of work
x/12+x/18=1
x/2+x/3=6
3x+2x=36
5x=36
x=36/5
7 minutes 12 sec.
check
36/5/12+36/5/18=1
3/5+2/5=1
1=1
ok
