I can only half answer this question, as it doesn't tell what form of distance is used
the equation is...
d=15g
Now lets solve for 1 gallon of gas
d=15g
d=15(1)
d=15
This means that for every 1 gallon of gas, 15 (insert missing unit of distance here) can be driven.
15/1=15
Answer:The constant of proportionality is 15.
