An airline passenger fell asleep halfway to her destinationwhen she awoke the distance remaining was half the distance traveled while she slept How much of the entire trip was she asleep?
Awake at start = 1/2 asleep + awake at end = 1/2 awake at end = 0.5 * asleep So by rearanging the equations we find that she was asleep for 1/3 of the total journey.
