The constant of proportionality is the ratio between the hours and the miles walked, which is always 1/2 in this case because Julian walks 2 miles in half an hour.
So the correct answer is:
D. (1, 1/4)
It takes Julian 1/2 hour to walk 2 miles. He decides to start working 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?
Hours | Miles walked
1/4 | 1
1/2 | 2
3/4 | 3
1 | 4
A. (1/4, 1)
B. (4, 1)
