In order to avoid heavy traffic, Antonio can drive home after working less than 7 hours or after working more than 9 hours. How can this be written as a single compound inequality?

“Less than 7 hours” means h < 7, and “more than 9 hours” means h > 9. Since Antonio can choose either condition, connect them with “or”: h < 7 or h > 9. This is choice B, “h is less than 7 or h is greater than 9.”
