<PRE><B>Question 165496</B>
It took Karla &amp; her helper 24 minutes to feed 18 cats. Working at the same rate, how long should it take Karla and 2 helpers to feed the 18 cats?
:
Treat this like a man-hour problem (girl-minutes in this case)
:
The feeding of the 18 cats required 2*24 = 48 girl-minutes
:
Let x = no. of minutes required, with three working
:
3x = 48
x = {{{48/3}}}
x = 16 min with 3 girls
:
;
Check 16 * 3 = 48 girl-minutes, the completed job requirement
