Answer:
A.) 1350 miles
Step-by-step explanation:
So, you know the amount of 1/2 of an in. is equal to 200 miles on the map. Next, you have to change the 1/2 to be a common denominator, so you change it to 4/8. Now, you have 4/8=200 mi. Okay, so, to get your answer, you divide the equation here __^^^ by 4 to get 1/8=50 miles. Then, you turn 3 and 3/8 into an improper fraction, which is 27/8, and do 50 times 27 to get 1350 miles.
