An aeroplane flies at a ground velocity (i.e. velocity relative to the ground) of 300 km/h N 30° W, in a wind blowing at a velocity of 50 km/h N 20° E. What is the velocity (speed and direction) of the plane relative to the ground? (Use a calculator and round the speed to the nearest km/h, and the corresponding angle to the nearest degree.)
