True or false: A pound of cheese weighs more than a pound of gold.

No Matter How You Slice It

What is the maximum number of parts a circle can be divided into using four straight lines?

Name That Tune

The clever butler needed some extra cash, so he tells his employer: “I know almost every song that has ever been written.” The master laughs at this, but the butler says “I am willing to bet you a month’s pay that I can sing a song that you have heard of with the lady’s name of your choice in it.”

“Deal,” says the employer. “How about my mother’s name, Felicity Jane Ashley?”

And so the bulter sang and earned himself an extra month’s pay. What song did he sing?

Row, Row, Row Your Boat

Kevin and Daniel were rowing their canoe along the river. In the morning they managed to row upstream at an average speed of 2 mph. They then stopped for lunch and a nice rest. In the afternoon, the pace was a little easier as they were now rowing downstream, and managed an average speed of 4 mph. The morning trip took them 3 hours longer than the afternoon. How far did they row upstream?

Name that tune

He sang “Happy Birthday,” of course!

Pound for Pound?

True! When it comes to pounds, there are two different standards: Avoirdupois weight and Troy weight.

Avoirdupois (av-ehr-du-poiz) weight is the series of units of weight based on 16 ounces to a pound. It is used for measuring almost everything— from cheese to feathers to boulders to compact cars.

Troy weight is based on 12 ounces to a pound. It is a specialty measurement used for measuring gemstones and precious metals, including gold.

Row, Row, Row Your Boat

12 miles

There are a number of ways of working this out; here is one:

If we assume the distance the rowed upstream to be D miles, we know the morning took (D ÷ 2) hours, and the afternoon took (D ÷ 4) hours, with a difference of 3 hours. So:

D/2 – D/4 = 3

Multiplying throughout by 2, and then 4, gives:

4D – 2D = 24, so 2D = 24

And:

D = 12 miles.

They rowed 12 miles upstream.
