Answer:
10 minutes
Explanation:
Mika can eat 21 hot dogs in 6 minutes and she wants to know how many minutes it will take her to eat 35 hot dogs.
This is a problem that can be used establishing a ratio. We know that she can eat 21 hot dogs in 6 minutes, therefore her ratio would be:
Now if she wants to know how many minutes it will take her to eat 35 hot dogs we can establish another radio where x will be the number of minutes it will take her:
Since the problem tells us that she can keep up the same pace when eating the 35 hot dogs, <u>we can make those two radios equal to one another and solve for x: </u>
Thus, it will take her 10 minutes to eat 35 hot dogs.
