On Saturday morning, Wendy watched one and a half hours of her favorite shows on television. During the shows there were 27 commercials. What is the unit rate of commercials per hour?

Question

9 hours per commercial
12 commercials per hour
14 commercials per hour
18 commercials per hour

Answer 1

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

Wendy watched 1.5 hours of her favorite shows, during which there were 27 commercials.

So, the unit rate of commercials per hour is 27 commercials divided by 1.5 hours, which equals 18 commercials per hour.

Therefore, the answer is 18 commercials per hour.
