Lots of people run with a pet dog. But some people run with wild wolves – and not just because it’s Halloween season! Scientists wondered whether wolves and dogs would get along and share food better if they ran together. So they built the world’s longest treadmill for them. The scientists then had to get the wolves and dogs to try the treadmill. They did this how you get any animal to do something: with treats. Now the dogs and wolves love it! We still have to see if the animals share better, but at least they’re all in great shape.
Wee ones: How many legs does a wolf have?
Little kids: If you, a wolf and a dog all run on the treadmill, how many legs do you have all together? Bonus: If you and the wolf then share 6 hamburgers equally, how many burgers does each of you get?
Big kids: If the wolf starts running at 2:00 pm and runs for 2 1/2 hours, when does it stop? Bonus:If the wolf can leap 5 feet at a time and the dog can leap 3 feet, which of them can leap from one end of the 30-foot treadmill to the other in fewer leaps — and how many leaps does it take?
Answers:
Wee ones: 4 legs
Little kids: 10 legs. Bonus: 3 burgers apiece.
Big kids: At 4:30 pm. Bonus: The wolf takes fewer leaps, since the leaps are bigger — just 6 leaps compared to the dog’s 10.
