Answer:
Shana ran 18 miles in a month
Step-by-step explanation:
Shana ran 6 miles in one week. This was one third of what she ran in a month
Let x be the miles she ran in a month
one third means 1/3
one third of miles she ran in a month is 6 miles
[tex]\frac{1}{3} x = 6[/tex]
Now we solve for x
To solve for x , we multiply 3 on both sides
1x= 18
so x= 18
So Shana ran 18 miles in a month
