Having a basic and fundamental knowledge of Physics, I was able to solve the Following question: Town A lies 20 km North of town B. Town C lies 13 km West of town A. A small plane flies directly from town B to C. What is the Displacement of the Plane? a) 33 km [W 33degrees N] b) 19 km [W 33degrees N] c) 24 km [W 57degrees N] d) 31 km [W 57degrees N] e)6.6 km [W 40degrees N] My answer was a). I got my answer by adding 20 and 13. Is this correct?
