Answer 2

To find the unit rate of commercials per hour, we can divide the total number of commercials by the total number of hours.

Explanation:

In this case, Wendy watched one and a half hours of her favorite shows, and during that time, she saw 18 commercials.

Step 1: Convert one and a half hours to a decimal. Since half an hour is equal to 0.5 hours, one and a half hours can be written as 1.5 hours.

Step 2: Divide the total number of commercials (18) by the total number of hours (1.5).

18 commercials ÷ 1.5 hours = 12 commercials per hour

Therefore, the unit rate of commercials per hour is 12 commercials per hour.
