Hi there!
Question 6)
The scale is 1 cm : 18km.
This means that for every 1 cm, there is 18 km
So, we are going to set it up like a proportion:
cm 1 9
km 18 x
Now we are going to cross multiple:
1*x=9*18
Solve for x:
x=152
Therefore, the answer is 152 km
question 8)
Yet again we have a proportion problem.
15 10
18 x
15x=180
x=12ft
Therefore, the answer is 12 feet.
Question 10)
This question is just like the other one!
3. 6
7. x
3x=42
x=14
Therefore, the answer is 14 feet
