An airplane starts from an airport and takes the route shown in figure below. The plane first flies to city A, located 170 km away in a direction 30.0° north of east. Next, it flies for 160 km 20.0° west of north, to city B. Finally, the plane flies 198 km due west, to city C. Find the location of city C relative to the location of the starting point.An airplane starts from an airport and takes the route shown in figure below.

Relative Velocity

It is a measurement of an object with regards to the other object which is moving or stable or stationary. For example, if we are traveling in a bus and the bus is moving at speed of 50km/hr, then our speed is according to the nearby passenger on the bus is zero. According to them, we are not moving. But if one person standing on the ground or road observes us from outside of the bus, according to him we are moving at a speed of 50km/hr and the bus is also moving at a speed of 50km/hr. Now, the motion is recognized by the observer, it depends on a frame of reference or observer. This is motion called relative motion.
