You're on a roll — let's tackle these questions. A) Geography/Navigation (i) State the location of D From the diagram, point D is located at 60^ South latitude and 50^ East longitude. The location of D is 60^ S, 50^ E. (ii) What is the difference in longitude between C and B? Step 1: Identify the longitudes of C and B. Point C is at 40^ W longitude. Point B is at 40^ W longitude. Step 2: Calculate the difference in longitude. Since both points are at the same longitude, the difference is 0^. The difference in longitude between C and B is 0^. (iii) Calculate the length of the circle of latitude 60^ S Step 1: Use the formula for the circumference of a parallel of latitude. The radius of the Earth is R = 3437 nm. The latitude is = 60^. The length of the circle of latitude L is given by L = 2 R . Step 2: Substitute the given values and calculate. Given = 3.14 and 60^ = 0.5. L = 2 × 3.14 × 3437 nm × 60^ L = 2 × 3.14 × 3437 nm × 0.5 L = 3.14 × 3437 nm L = 10799.98 nm The length of the circle of latitude 60^ S is 10799.98 nm. (iv) Calculate the distance between B and D along the latitude 60^ S Assumption: Point B is at 20^ N, 40^ W, which is not on latitude 60^ S. It is assumed the question meant to ask for the distance between points C and D along latitude 60^ S, as both C and D are on this latitude. Step 1: Identify the locations of C and D and their common latitude. Point C: 60^ S, 40^ W Point D: 60^ S, 50^ E Common latitude = 60^ S. Step 2: Calculate the difference in longitude ( ). Since one point is West and the other is East, add their longitudes. = 40^ + 50^ = 90^ Step 3: Apply the formula for distance along a parallel of latitude. The distance d is given by d = × 60 nm/degree × . Step 4: Substitute the values and calculate. 60^ = 0.5. d = 90^ × 60 nm/degree × 60^ d = 90 × 60 × 0.5 nm d = 2700 nm
