Make a quick plot of the cumulative times vs. cumulative distances for Student 2. To clarify, your first data point would be (400 m, 64 s) and your second data point would be (800 m, 128 s), etc... From the slope of a linear regression of your graph, calculate the average speed (in m/s) of Student 2 as he runs the 6 laps. Round your answer to 2 decimal places.
Lap times (s) for 2 students running on a track
Time 1 
Time 2 
Time 3 
Time 4 
Time 5 
Time 6 

student 1 
55 
112 
162 
218 
273 
333 
student 2 
64 
128 
192 
260 
331 
393 
From the table given, the data points will be as shown below. for student 2.
Position  Time 
400  64 
800  128 
1200  192 
1600  260 
2000  331 
2400  393 
If we draw a graph with time on the X axis and distance travelled on the Y axis,
the slope of the graph will be equal to the average speed.
Here,
The graph is shown below.
From the graph's linear fit,
Average speed = slope = 6.0273 m/s
