Worker W produces n units in 5 hours. Workers V and W work independently but at the same time, produce n units in 2 hours. How long would it take V alone to produce n units?	Options:
A) 8/3 hours	B) 10/3 hours	C) 11/3 hours	D) 12/3 hours	E) 18/3 hours
w's 1 hours production=n/5   (w+v)'s 1 hours production=n/2   v's 1 hours production   n/5+V=n/2   v's 1 hours production=n/2-n/5   =3n/10   n/(10/3)   ans=10/3 hours   ANSWER:10/3 hours
