Zack is taking a test in which he answers questions at a rate of question per minute. If Q represents questions and M represents minutes, which of the following equations describe this rate relationship?

Q = × M
M = 2 × Q
M = × Q
Q = 2 × M

I think that it is the third one. Please let me know if I was correct or wrong. :-)

Step-by-step explanation:

The second equation describe the relationship between the rates. M= 2 x Q.

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
