The constant of proportionality is found by dividing the total time by the number of laps.
For example, for 6 laps, the total time is 4.8 seconds.
4.8 / 6 = 0.8
Since all the values of total time divided by the number of laps equal 0.8, the constant of proportionality is 0.8.
Therefore, the correct answer is 0.8.
The table below shows a proportional relationship between the total amount of time it takes a swimmer to swim different numbers of laps.
