Question 41942
I did it with a diagram...
Since she fell asleep halfway thru the trip, she had halfway to go...
Now when she awoke the distance remaining must have been 1/3 of the half, since double that was what she slept...so
She was awake for 1/2 the trip, then
She slept for 1/3 of the trip, then
She was awake for last 1/6 of the trip.
The answer is 1/3.
