Answer:
D, 30%
Step-by-step explanation:
you move the decimal point twice to the right
On the map the ratio is 3cm:4km
The map distance is 24cm
Our overall ratio is 3 : 4
24 : ?
We can find the scale factor by doing 24/3 which is 8. Then do 8 x 4 = 32km
The actual distance is therefore 32km
15=3b
15/3 = 3b/b
5= b
Isolate the variable by diving 3 on both sides
