Answer:
It would take him 11 hours.
Explanation:
What you want to do is found out how many miles he drove in 1 hour. In order to do that, divide 189 by 7. By doing that, you get the answer of 27. Now that you have how much he drove in 1 hour. To find out how much it would take him to drive 297 miles, you also divide 297 by 27 to get 11. Which means that it would take him 11 hours to drive 297 miles. I hope this was helpful.
