Answer:
≈13degrees
Step-by-step explanation:
It is given that Two cities A and B are 1400km apart and lie on the same N-S line. The latitude of city A is 23 Degrees. Then,
Using the formula, 
where s is the distance between the two cities and r is the radius of the earth,thus substituting the values, we get
⇒
Therefore, 
⇒
⇒
Thus, the latitude of B is=12.53 degrees≈13degrees
