At midnight, the depth of snow on a road is 6 cm. The snow falls at a steady rate and the depth increases by 2 cm per hour until 4 am, when it stops. At 10 am the snow starts to melt, so the depth decreases at a constant rate and by 3 pm, the road is clear A graph of the depth of snow (in cm) against time since midnight is shown below. The horizontal scale is marked in hours using the 12 hour clock Depth (cm) 4 14- 12- 10- 8- 6- 4- 2- 0 2am 6am 10am 2pm Time (hours) Choose the TWO correct options about this graph from the following list 6pm Select one or more. The line is horizontal between the times of 4 am and 10 am Between the times of 10 am and 3 pm, the gradient of the line is positive The intercept on the horizontal axis represents the depth of snow at midnight The gradient of the line between midnight and 4 am represents the time when the snow started to fall The maximum depth of snow was 15 cm. DFrom midnight to 4 am, the gradient of the line is 6 cm/h Between 10 am and 3 pm, the gradient of the line is about -2.8 cm/h At midnight, the depth of snow on a road is 6 cm.
