Puzzle 1 


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.
