Helen would travel 63 miles in one hour. Also known as - || 63 miles per hour ||
Explanation:
In order to find how far she would travel in one hour we first have to see how far she traveled in all. Which would be 567 miles. We know she took 9 hours to travel this far. By dividing 567 miles by 9 hours then we can find out how far she traveled in one hour. So 567/9 = 63.
Have a good rest of your day. I hope this helps! ^^
