Mental Floss 323

The answer to last week’s challenge is: Q: A Doctor gives you three pills and tells you to take one every half hour. How long will the pills last?

A: One hour.

This week’s thinking challenge is …

Q: There is a low railway bridge in your suburb. One day, you see a large truck waiting near the underpass. The driver tells you that his truck is 5cms higher than the indicated height of the gap. How can you help him to get through the underpass?

The answer along with a new challenge, next week.

Have an excellent weekend!
