Imagine that you can tie a string tightly around a polygon. if the polygon is convex, will the length of the string be equal to the distance around the polygon? what if the polygon is concave? explain.

In this question, a person can read 24 pages in 1/3 of an hour. Since the hour is divided into 3 parts, we must also multiply 24 by 3 to complete 1 hour. 24 pages times 3, is equal to 72 pages per hour. Therefore, the reading rate of the person mentioned in the problem is 72 pages of a book per hour.
