Draw a distance-time graph with 2cm to 10 units for the y-axis : Mrs Chuong leaves home at 08:00 and drives at a speed of 50km/h. After 1/2 hour she reduces her speed to 40km/h and continues at this speed until 09:30. She stops from 09:30 until 10:00 and then returns home at a speed of 60km/h. Use the graph to find the approximate time at which she arrives home.
