Answer:
it took Seth to walk each mile at a rate of 0.5 miles per hour.
Explanation:
To find Seth's rate of walking per mile, we can use the formula:
rate = distance / time
Here, the distance is 1 mile (since we want to find Seth's rate per mile) and the time is 2 hours to walk 6 miles. So we can plug these values into the formula:
rate = 1 mile / 2 hours = 0.5 miles per hour
