On her way to visit her parents, Keegan drives 480 miles in 6 hours. What is her average rate of speed in miles per hour?

That’s a hell of a question but I think you need to multiply 480, 6 times

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
