If Peter can travel 576 miles in 12 hours, then to find his speed, we just have to divide 576 by 12. This will give us his speed in miles per hour:
576/12 = 48 miles/hour
If we know he can travel 48 miles in one hour, then to find distance traveled in 14 hours, just multiply the speed by 14.
48 * 14 = 672 miles
A: 672 miles
