Here's how to solve the problem step-by-step: Given: Radius of the Earth, R = 6370 km. Speed of plane S = 420 knots. Points: P(40^N, 45^W) Q(40^N, 45^E) T(35^N, 135^E) a) Find the distance from P to Q in km. Step 1: Determine the difference in longitude () between P and Q. P is at 45^W and Q is at 45^E. Since they are on opposite sides of the Prime Meridian, we add their longitudes. = 45^ + 45^ = 90^ Step 2: Identify the latitude () for P and Q. Both P and Q are at 40^N latitude.
