Dog Train

September 18, 2017

Dogs love to ride in the car with their head sticking out the window. So it isn’t surprising that they also like riding trains. Eugene Bostick, an 80-year-old man in Texas, built a dog train that he pulls with his tractor. He takes care of dogs he’s found who don’t have a home. When he had just a couple of dogs, he’d let them ride in the tractor with him. But after a few more dogs showed up, he couldn’t hold them all in his lap any more. So he connected a bunch of blue carts, and ta-da, he had a dog train! Now he gives the dogs a train ride twice a week.

Wee ones: What shape are the tractor wheels?

Little kids: If there’s 1 dog in each cart, how many dogs are in front of the dog in the 7th cart?  Bonus: If 3 carts are carrying 2 little dogs each, while the rest of the 8 carts each hold 1 dog, how many dogs are riding the train?

Big kids: If the dogs ride every 4th day starting on Sunday of the 1st week, in what week do they get to ride on a Tuesday?  Bonus: If the dogs ride twice a week, how many rides do they get in a 52-week year?

 

 

 

Answers:
Wee ones: Circles.

Little kids: 6 dogs.  Bonus: 11, since there are 3 extra dogs beyond the usual 8.

Big kids: In the 3rd week (Sunday/Thursday, then Monday/Friday, then Tuesday/Saturday).  Bonus: 104 rides.
