Worker W produces n units in 5 hrs. Worker V and W, working independently but at the same time, produce n units in 2 hrs. how long would it take V alone to produce n units?
options
1.1 hr 26 min
2.1 hr 53 min
3.2 hr 30 min
4.3 hr 20 min
5.3 hr 30 min

• 4. 3hour 20mins.
  W produces unit in 1 hour = n/5
  V and w together produces unit in 1 hour = n/2
  From this data equation is
  (n/5) + (n/v) = (n/2)
  (n/v) = 3/10
  V = 10/3hours
  Means 3 hour 20mins.
