Question

Brenda and her family were driving to her grandmother’s house during a holiday. During the drive, Brenda fell asleep halfway through the? trip. When she awoke, her family still had to  travel half the distance that she had traveled  while she was sleeping. For what fraction of  the entire trip had Brenda been asleep?

Answer 1

Let the call whole trip 1.

They had already half (1/2) driven when Brenda fell
asleep.
There was half (1/2) left to travel.
Let fraction of distance traveled while Brenda was asleep entire trip = d
Left to travel after she woke up = d/2

So d/2 + d = (1/2)

      3d/2 = (1/2)

      3d = 1

        d = 1/3
