Here is the question. all I need is basic and concise explanation, give me the values and say whether to convert km/h to secs(m/sec) stating the hows and whys.Would the graph be curved, how do i find the slop and intercept?Also tell me how tofind the speed and acceleration from the graph.

The speedometer of a motor-car showed the following speeds in km/h at the end of successive intervals of 3 secs:
38.9, 52.8, 64.4,73.6, 80.9, 86.1, 90.0, 92.5. Plot the velocity-time graph in convenient units and find from the graph the disatance in km covered while the speed increased from 80 to 90km/h. and the accelerations when the speeds are 50,70 and 90km/h
