Summary

2 hours (I think, did the math in my head)

2291

Correct!

I didn’t do it in my head and I used an embarrassing number of lines.

2292

I’ve seen enough of those problems now to figure out the important statistic is the worker-hours, and since 3 x 6 = 18, they did 1,620 envelopes / 18 worker-hours. I got lucky to recognize that 1,620 is 10% below 1,800, which would have been 100 envelopes / worker-hour, so they were 10% below 100, or 90. Productivity is 90 envelopes / worker-hour. And since 720 / 90 = 8 worker-hours to get 720 envelopes, we need 8w-h / 4 w = 2 hours.

Correct.

Yeah, I kept wanting to make the first one be potluck, which slowed me down a bit.

01/31/2022 Suit Yourself

Four playing cards, one of each suit (a red heart, a red diamond, a black spade, and a black club), lie in a row on a table. They are a Jack, a Queen, a King, and an Ace. Using these clues, can you determine the cards and their order?

  1. The spade sits between the club and the King with no cards intervening
  2. The Jack is immediately to the right of the diamond
  3. The leftmost card is the Queen, which is a red card
  4. The Ace is not a spade

1/31, but probably wrong

Queen of hearts - King of diamonds - Jack of spades - Ace of clubs

02/01/2022 Changeovers

A changeover is a pair of words like WRATH and WATCH in which a letter in the first word moves to a position later in the word and changes to a new letter to form the second word. Here, the R moves and changes to a C. In each row below, the clues lead to two 5-letter words with a changeover. Write the letter-change pair (such as R C in the example) in the boxes in the center. When you’re finished, read the two columns formed by the letter pairs to see a vehicle.

Who the heck has ever heard of Arles? It’s not a city. Its a small town that never has had more than 53,000 people in it. According to wikipedia, Vincent Van Gogh only spent 16 months there, so even he only half-heard of the place. (You see what I did there? Half-heard… because he only had 1 ear.)

They got a lot of Eiders in Arles?

2306

I’ve heard of it. Never knew that Van Gogh lived there, but it was a thing that worked with the other answer, so :man_shrugging:

Same. Too many years of French class gave me a passing knowledge of French towns.

In this maze, start on the white circle in the top-left corner and end on the white square in the lower-right corner as you follow these rules:

  1. Move from cell to adjacent cell up, down, or sideways but never diagonally.
  2. The cell you move to must contain the same shape (square or circle), the same shading (blue or white), or both the same shape and the same shading as the one you’re currently on. For example, if you’re on a white circle, you can move to an adjacent cell containing a white circle, a blue circle, or a white square.

Can you find the path?
