Final answer:
Hans would take 11 hours to drive 693 miles at the same rate he drove 819 miles in 13 hours.
Step-by-step explanation:
To find out how long it would take Hans to drive 693 miles at the same rate, we need to determine his average speed. We can do this by dividing the total distance he traveled by the time it took him. Hans drove 819 miles in 13 hours, so his average speed is 819 miles / 13 hours = 63 miles per hour.
Now we can calculate the time it would take for him to drive 693 miles. We know his average speed is 63 miles per hour, so we can divide the distance by the speed: 693 miles / 63 miles per hour = 11 hours.
