Is it nice to pose a math problem on a Sunday?

I had a stationary bike. After a few years, I had done 12,500 miles on that bike — halfway around, at the equator. But I wondered what degree of north latitude would be12,500 miles long (so I could see what cities were at that latitude). I thought I’d figured it out, but wanted validation; it had been a long time since I was in junior high. We were having parent-teacher conferences, so I asked the 7th grade math teacher. She took the problem and said she’d get back to me. Never did. When my daughter asked about it, she said she’d lost the problem — but didn’t ask for another copy.

I repeated this with math teachers each year. Never got an answer.

Can you finnish this problem?

Thanks to Chemgal for this Zits, which earns a LOL-Ewww!

And here is your LOL-CIDU-Geezer for the week!

Another CIDU-LOL, or Arlo-LOL, and the one calling for the category tag about “There must be a popculture reference that will clear it up instantly” — if you can see putting the chess world in “popculture”. Yes, something upsetting happened recently in the world of chess, and then Twitter has its way with answering some of the questions raised.

Thanks to dollarbill for this DSOH, featuring one of their favorite tropes, counting sheep.
