To determine if the table shows a proportional relationship, we need to check if the ratios between the quantities are the same. Let's calculate the ratios:

10/2 = 5
20/4 = 5
30/6 = 5

The ratios are all equal to 5, so the relationship is proportional. However, none of the answer choices correctly identify the constant of proportionality. The correct answer is not provided.

To find the unit rate, we divide the distance (in meters) by the time (in seconds). Let's take any row from the table to calculate the unit rate:

Distance: 30 meters
Time: 6 seconds

Unit rate = Distance / Time = 30 meters / 6 seconds = 5 meters per second

Therefore, the unit rate of the relationship shown in the table is 5 meters per second.
