Hello there, and thank you for posting your question here on brainly.
Short answer: 280 miles.
Why?
You can find this out by finding out how much 1 in is by dividing 200 by 5. (200 / 5 ==> 40) So 1 in = 40 miles. Now, we multiply that by 7, so we can find out how much 7 in would be. (7 * 4 ==> 280) 7 inches on the map represents 280 miles.
Hope this helped you! ♥
Add all the number, and then divide it by number of numbers.
for example, 1, 2, 3, 7, 10
(1+2+3+7+10)/5
23/5 = 4.6 The average is 4.6
