The equation of the circle:
Answer:
The question is incorrect. please write your coordinates in the form (x, y).
Answer:
600 miles
Step-by-step explanation:
Since the scale is given as 1 inch = 50 miles
Then to get the distance when given 12 inches in a map we do cross multiplication as follows
1 inch = 50 miles
12 inch=x miles
By cross multiplication
1 inch*x miles=50 miles *12 inches
Making x the subject of formula then
X=50*12/1=600 miles
Therefore, the actual distance is 600 miles
