5. gradient of the graph DYNAMICS An aeroplane flies from X to Y as shown in the sketch. If the journey takes 15 minutes then calculate: 15minate = 9254 මන්ත්‍රී (a) the distance from X to Y (b) the displacement from X to Y the average speed of the aeroplane from X to Y the average velocity of the aeroplane from X to Y (e) draw a displacement/time graph of the journey (f) what does the gradient of the graph indicate? (c) (d) Complete: 28 000 kg 11 11 .... N = ..T kN 60 km ox X 20 km 0> 10 km​
