Answer 1

See below

Explanation:

Hi, Kelsey. It would be too easy to just give you the answer. I want you to understand how to do it. And more importantly, how to problem-solve. I'm an old man who's raised 7 kids, humor me, please.

1) They're all units of some kind. If you don't know what each word means, look them up.

2) You'll find that three of them are units of time, and one is a unit of distance. That will be the "odd one out."

Take care, and good luck in high school.
