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 [tex]\frac{miles}{1 hour}[/tex], we have to simplify the rate we already have.
The given rate is [tex]\frac{560}{5}[/tex], and in order to get the unit rate, we simply have to simplify the fraction by dividing both sides by 5:
[tex]\frac{560/5}{5/5}[/tex] = [tex]\frac{112}{1}[/tex]
Now we know that the unit rate is [tex]\frac{112 miles}{1 hour}[/tex]
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 [tex]\frac{112 miles}{1 hour}[/tex], 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!
[tex]\frac{112 miles}{1 hour}[/tex] * 9 = 1008
The jet can fly 1008 miles in 9 hours, and the unit rate is [tex]\frac{112 miles}{1 hour}[/tex].
Good luck! If you have any questions, just ask! :))
