Puzzle 14

Last week I travelled from London to Leeds, a distance I measured as 174 miles.

I started at 9.15am and completed the journey with an average speed of 40 miles per hour.

On the way back, in the evening, I travelled exactly the same route, starting at 5.15pm. The traffic was light, and I completed the journey with an average speed of 60 miles per hour.

What was the overall average speed for the round trip?

The answer is not 50 mph.

Puzzle 15

What is significant about this paragraph:

I once found two tiny ferrets, tired, looking sorry for themselves, covered in dirt. I decided to help the poor critters by putting them in the town zoo's 'ferret rinsing box', then rinsing them off using some tinctured liquid. They soon seemed much more pristine, much brighter, much more cheerful. Within two weeks I set them free, returned into the wild, they seemed very delighted with this. I, of course, enjoyed it very much.
