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 \frac{miles}{1 hour}, we have to simplify the rate we already have.

The given rate is \frac{560}{5}, and in order to get the unit rate, we simply have to simplify the fraction by dividing both sides by 5:

\frac{560/5}{5/5} = \frac{112}{1}

Now we know that the unit rate is \frac{112 miles}{1 hour}

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 \frac{112 miles}{1 hour}, 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!

\frac{112 miles}{1 hour} * 9 = 1008

<u>The jet can fly 1008 miles in 9 hours, and the unit rate is \frac{112 miles}{1 hour}.</u>

Good luck! If you have any questions, just ask! :))

Which question can be answered by finding 212÷23? A. How many 23-meter long pieces of ribbon are needed to have a total of 212 m
SOVA2 [1]
The correct answer is the letter A because a division problem shows a total amount being broken into equal parts.

Choice a talks about how many parts it would take to get the total of 212 m of ribbon.

This choice includes the parts and total information.

Hello from MrBillDoesMath!

Answer:

Number marbles >= 5

Discussion:

The only certain thing we can say is the jar contains at least 5 (green) marbles.  The table  shows probabilities, not certainties, and is no guarantee that any other marbles even exist  in the jar,

Thank you,

MrB
