Hint
It doesn't matter how far it was to Manchester, so you can use any distance.

Answer
Billie.

Reasoning
If we call the one way distance T, we know that:

On the way there, Alex drove 90 miles, and Billie drove (T − 90) miles.

On the way back, Alex drove (T − 100) miles, and Billie drove 100 miles.

So, in total, both ways:

   Alex drove 90 + (T − 100)
      = T − 10

   Billie drove (T − 90) + 100
      = T + 10

Therefore, Billie drove 20 miles more than Alex.

Answer
2,300 miles.

Take the alphabetic position of the first and last letters, add them together and multiply by 100. S = 19, D = 4, 19 + 4 = 23, 23 x 100 = 2,300.
