How many squares would there be?

If you were to construct a 7 x 7 checkered square (i.e., a 7 x 7 chess board), how many squares would there be in total? (Hint: it's not 49)

An oldie but a goodie

A man traveled by car to a destination 25 miles away. The journey was made between 7 and 9am, so the roads were congested and progress was slow. The journey took 75 minutes, which means that his average speed was 20 miles per hour. He took the same route on the return and traveling in the middle of the day made faster time: his return journey lasted just 25 minutes, meaning that his average speed fro the return journey was 60 miles per hour.

What was his average speed for the two journeys combined?

What was his name, again?

What did the 'S' stand for in President Harry S. Truman's name?


This has been a busy weekend, so consider this my question for Saturday and Sunday.

Thanks!

Random number

Try thinking out a random 3-digit number and writing it twice on a piece of paper, forming a 6-digit number (for example the number is 123, than you will have to put down 123123 on the paper). Now divide this 6-digit number by 7. There will be no remainder, I guarantee. Now divide the result by 11. No remainder again, I guarantee. Now divide the new result by 13. What happened?

I'll be there in a jiffy!

How much time is a jiffy?

PS: This is a trivia question.

Fire Trivia

Why are walls often "sweaty" after a fire? (This is a trivia question, not a riddle or a joke).

May I?

What does this represent?
"May I have a large container of coffee Thank You."

And no, I'm not looking for an order at your local restaurant...
