The solution is 6, signifying the instances where distinct time-situp pairs are identifiable on the graph.
The graphical representation indicates that the x-axis corresponds to time, while the y-axis represents the number of situps.
Notably, at t=20 seconds, only one data point is discernible, eliminating the possibility of obtaining three simultaneous situp values.
Consequently, the total number of data points amounts to 6.
Therefore, the solution is 6, signifying the instances where distinct time-situp pairs are identifiable on the graph.
This interpretation aligns with the understanding that at t=20 seconds, the data point is treated as a singular entity rather than three distinct values, leading to the conclusion that there are six discernible data points overall.
