Answer :
Final answer:
To find the distance between the cities, we can use the formula for arc length on a sphere. The distance is 360,000 miles.
Explanation:
To find the distance between the cities, we can use the formula for arc length on a sphere. The formula is given by:
Distance = radius x angle
In this case, the angle is 90° as one city is due north of the other. The radius is 4000 miles.
Therefore, Distance = 4000 miles x 90° = 360,000 miles.
Rounded to the nearest mile, the distance between the cities is 360,000 miles.
