The position of two towns X and Y are given to the nearest degree as X(45° N, 10° W) and Y (45 N°, 70° W).
Find
70-10 =60
Find:
(a) The distance between the two towns in
(i) Kilometers ( take the radius of the earth as 6370)
60/360 *2*3.142*6370*cos(45)
= 4717.47km

(ii) Nautical miles ( take 1 nautical mile to be 1.85 km)

(b) The local time at X when the local time at Y is 2.00 p.m.

(ii) just divide (i) by 1.85
(b) since 360° = 24 hrs, each time zone occupies 15°
X is 60° east of Y (time is later)
