Concept:Distance along the same meridian is calculated using the angular difference in latitude, where each degree equals about $111\text{ km}$.Explanation:Town Y is located at latitude $40^\circ\text{N}$, while Town Z is located at latitude $10^\circ\text{S}$.Since the two towns are on opposite sides of the Equator, their latitude difference is the sum of the two angles.So, the total angular difference is:$$40^\circ + 10^\circ = 50^\circ.$$One degree of latitude is approximately $111\text{ km}$.Therefore, the distance between the two towns is:$$50 \times 111 = 5550\text{ km}.$$Answer:$5550\text{ km}$, which is Option D.
