If he run 5.9miles each day, about how much does he run every month

For 30 days 177 miles

For 31 days 182.9

For 29 days 171.1

For 28 days 165.2

We know one thing, 5.9 miles is the amount per day.

Now, to solve a problem like this, we need to determine how many days in a month.

Well, usually, the majority amount of months have 30 days. So I will therefore use 30 days to solve.

5.9*30 = 177 miles

But wait ... since it says 'about', it means that we must put this sign : - ≈

Final answer: - He runs about 177 miles a month.
