Petals Around the Rose

Here are five rolls of dice, with their score.

Roll #1 – Score: 6

Roll #2 – Score: 4

Roll #3 – Score: 4

Roll #4 – Score: 8

Roll #5: 0

This is what you know:

1. The name of this game is significant (Petals Around the Rose)
2. The answer is always even

How is the score determined?

The solution is to count the dots (petals) surrounding the center dot (the rose).

Only odd numbers have a center dot, so even numbers (2, 4 and 6) are worth zero.

1 doesn’t have any surrounding dots, so it too is worth zero.

The three has two dots surrounding the center, so it’s worth two.

A five has four petals around the rose making it worth four.

The Greatest God

The Pharoah asked, “Who is the greatest god?”

“I am not,” said Horus.
“Anubis is,” said Isis.
“Isis is lying,” said Anubis.

Only one god was telling the truth and the other two were lying.

Who really is the greatest god?

Horus is the greatest

“I am not,” said Horus = LIE
“Anubis is,” said Isis = LIE
“Isis is lying,” said Anubis = TRUE

The Bikes and The Bee

Two bikes are traveling toward each other at a constant speed of 10 mph. When the bikes are 20 miles apart, a bee flies from the front wheel of one of the bikes toward the other bike at a constant speed of 25 mph. As soon as it reaches the front wheel of the other bike, it immediately turns around and flies at 25 mph toward the first bike. It continues this pattern until the two bikes smush the bee between the two front tires.

How far did the bee travel?

25 miles.

The easiest way to think about this is to consider the time. The bikes will take 1 hour to touch, given that they start 20 miles apart and are each traveling toward each other at 10 mph.

Therefore the bee is buzzing back and forth at 25 mph for 1 hour.

Debbie’s Dragster

Debbie starts driving her dragster from rest and constantly accelerates to 60 mph in 10 seconds. How far does she travel in those 10 seconds?

1/12 mile

Ten seconds is 1/6 of a minute and 1 minute is 1/60 of an hour, so 10 seconds is 1/360 of an hour.

If you graph her trip with the speed on the y-axis and the time on the x-axis, you get a triangle with height of 60 mph and width of 1/360 of an hour. To calculate the area of the triangle, you multiply 1/2 × 1/360 × 60 = 1/12.
