Answer:
Zach walks 154 miles if he works 22 days.
Explanation:
Zach walks 7 miles everyday to deliver the mail to the post office.
To find out how many miles he will walk if he works for 22 days:
You multiply 7 by 22 because you are trying to find how many miles he will walk in 22 days and you know that he already walks 7 miles everyday.
Since 7 lots of 22 is 154, Zach walks 154 miles in that month.
