Alice and Bob working together can complete a task in 2 hours.
If Alice works with Charlie they can do the same task in 3 hours.
If Bob works with Charlie they can complete it in 4 hours.
If Alice, Bob and Charlie were to work together on the task how long would it take to complete.
Assume the individuals work at the same rate regardless of who is working ( i.e. the work to complete the task is parallelizable )
