The constant of proportionality represents the ratio between the distance Julian walks and the time it takes him. In this case, Julian takes 1/2 hour to walk 2 miles. So, the ratio of distance to time is 2 miles / 1/2 hour, which can be simplified to 4 miles/hour.
Therefore, the correct answer is:
(4, 1)
It takes Julian 1/2 hour to walk 2 miles. He decides to start walking in his spare time, but because he wants to make sure he has enough time to go a desired distance he created the data table. At which ratio does the constant of proportionality appear?
