If Noah is running 6 miles an hour then we know that for every hour, he is running 6 miles. You have to multiply each hour he’s running by 6.
For the last three answers, since they give you how much time he ran, you have to divide by 6 miles.

1 = 6
1/2 = 3
1 1/3 = 8
(I can’t see the fourth one)
1 1/2 = 9
3/4 = 4 1/2
