Answer:
Step-by-step explanation:
The constant of proportionality 'k' between two variables ( one independent and one dependent ) is given by :-

In the given table, independent variable = Days
Dependent variable = Total Miles
From first row, Days = 3
Total Miles = 
Then, the constant of proportionality in the table

Hence, the constant of proportionality in the table is
.
All of the above. Sorry if this is wrong but in 99% sure it isn’t!!
