Mental Floss 306

88 69 11

The answer to last week’s challenge is: Q: What do the numbers 11, 69, 88 all have in common?

A: They read the same right side up and upside down.

This week’s thinking challenge is …

Q: An iron horse with a flaxen tail. The faster the horse runs, the shorter his tail becomes. What is it?

The answer along with a new challenge, next week.

Have an excellent weekend!
