In order to figure out how far a plane could fly in 9 hours, we have to use unit rate.
(Unit rate is the value you get in one unit, such as Miles Per Hour, or Dollars Per Pound)
In order to figure out , we have to simplify the rate we already have.
The given rate is , and in order to get the unit rate, we simply have to simplify the fraction by dividing both sides by 5:
=
Now we know that the unit rate is
Now, let's use an example.
If a car was going 60 miles per hour for 3 hours, how far would it go? In this case, you'd simply have to multiply 60 and 3 together. The car would travel 180 miles.
Back to the question.
If the jet travels , how far would it fly in 9 hours?
If you looked at the example, then you already know that you simply have to multiply 112 and 9!
* 9 = 1008
<u>The jet can fly 1008 miles in 9 hours, and the unit rate is .</u>
Good luck! If you have any questions, just ask! :))
