Answer:
7500 ft and 11250 ft
Step-by-step explanation:
Let's start by converting 30 inches to feet. There are a lot of ways to do this, by this is the method I find to be convenient.
1 in = 250 ft
1 in * 30 = 30 in.
250 ft * 30 = 7500 ft.
^ this method only works because one of the conversion factors is equal to 1.
Try again with 45
1 in * 45 = 45 in
250 * 45 = 11250 feet
