explain how to write 20 miles divided by 4 hours as a unit rate
If that's distance traveled per unit of time it would be
20miles per 4 hrs but since it's usually compared per hour...
20/4= 5 miles
so every hour you travel 5 miles
5miles per hour
Note the formula for such a question is....
distance = rate * time
d = rt
rate = distance / time
r = d/t
