Worker W produces n units in 5 hours. Workers V and W, workers independently but at thesame 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:
A) 1 hr 26 min  B) 1 hr 53 min  C) 2 hr 30 min  D) 3 hr 30 min  E) 3 hr 20 min
V and W produce n units in 2 hours. So they produce n/2 units in 1 hour.   W produces n units in 5 hrs. So he alone produce n/5 units in 1 hr.   So V produces in 1 hr. = n/2 - n/5 = 3 n/10 units.   V produces n units in 10/3 hrs. which is 3 hrs 20 min.   ANSW3 hr 20 minR:3 hr 20 min
