Answer:
The proportion that can be used is
<u>2 inches</u> <u>30 inches</u>
15 miles x
Step-by-step explanation:
If 15 miles is 2 inches and 30 divided by 2 is 15, you have to multiply 15 by 15 to figure out how many miles 30 inches is. Because 15 x 15 = 225, 30 inches is 225 miles. Therefore, x = 225.
To square a number, multiply the number by itself.
