Ms. Baumgartner can travel miles in hours. At this rate, how many hours would it take her to complete an -mile trip? Show how you know.

First, you can determine the speed (or the rate).

At this speed, how long will it take to travel 810 miles?

Another method would be to set up and solve this proportion.

Why would this proportion make sense? Try it and see if you get the same answer.
