Draw a distance-time graph (the scale is attached in the reply below) : 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.
***the answer in my book is 11:05 but i dont know how to get it. :/
