Hi guys, having some trouble with this question as I cannot see where I am going wrong. Very simple question but I must be misunderstanding something.

The following table shows how the velocity of a car varied with time:

Velocity (km/h) 0 19 35 48 48 27 0

Time (s) 0 3 6 9 12 15 18

Assuming these speed values to be joined by straight lines, plot a graph of speed against time and determine the total distance travelled.

s = dxt

Area under graph = distance travelled

I assumed this question would be as simple as finding the area under the graph to get the total distance travelled. So I went about drawing my graph along with converting all the values for speeds into (m/s). I have attached a picture of what my graph looks like in case anyone would like to see it (its a bit messy). I'm sure there is a very simple explanation to where I am going wrong but I'm just not seeing it myself.

Thanks in advanced guys!
