Concept:Distance along a meridian depends on the difference in latitude.Each 1∘ of latitude is roughly 111 km.Explanation:The first place is at 11∘N and the second is at 5∘S.Since they lie on opposite sides of the Equator, add their latitudes to obtain the total angular distance.Total latitude difference =11∘+5∘=16∘.Approximate distance =16×111=1,776 km.Answer:C. 1,776 km
