Answer:
look at explanation
Step-by-step explanation:
To solve all of these questions you just need to scale. While scaling you can divide or multiply.
1. (divide by 4 to get unit rate)
unit rate =
2. If it takes one hour to travel 40 miles, then we don't have to scale or anything. We know , the answer is...
"It'll only take one hour to travel 40 miles. This is correct because the unit rate is . "
3. Knowing that the constant speed of the plane is , we can scale then add half of the unit rate to get our answer.
x 3 = 800 x 3 = 2400
then add half of unit rate which is = 400
so, our answer is
4. <--- ( divided by 2) ( multiplied x 2.5) --->
To get an easier way to find the answer, if possible you can scale back farther than the 1 hour mark.
Elmer would take 2 and a half hours to ride 15 km.
5. The boys speed is . All we need to do is divide by 2. = 4

Amount of lemonade in each pitcher = Seven quarters = gallons
We have to determine the amount of lemonade in 5 and 1/2 pictures.
First, we will determine the amount of lemonade in 5 pitchers.
So, Amount of lemonade in 5 pitchers = = gallons.
Now, we will calculate the amount of lemonade in half of the pitcher = = gallons
Total amount of lemonade in 5 and half a pitcher =
LCM of 4 and 8 is '8'.
=
= gallons.
Therefore, the total amount of lemonade in 5 and 1/2 pictures = gallons = gallons.
I used the calculator and it said 22.5 so idk exactly its either 22 or 23. Hope this Helps! :P
