I saw a set of puzzles today like:
"60 M. in an H."
(Solution: 60 minutes in an hour)
One of them was:
"24 M. on a B. T."
Can't figure that one out.
It's possible that it was supposed to be written "in a" rather than "on a" but I can't think of one to fit that either.
As a reward for anyone who solves it, I'll post a few more for you to solve."
thx,
