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? Choose the correct choice from the following answers.
A) 10/8
B) 10/3
C) 10/6
D) 10/2
E) 10/1
Explanation:   w's 1 hours production = n/5   (w + v)'s 1 hours production = n/2   v's 1 hour production = n/5 + V = n/2   v's 1 hour production = n/2 – n/5 = 3n/10= n/(10/3)   Ans = 10/3 hours   \Answer: 10/3
