B (2, 3); If Jim runs 2 minutes, he completes 3 laps.(2, 3); If Jim runs 2 minutes, he completes 3 laps.
C (3, 2); If Jim runs 3 minutes, he completes 2 laps.(3, 2); If Jim runs 3 minutes, he completes 2 laps.
D (3, 2); If Jim runs 2 minutes, he completes 3 laps.
he completes 3 laps.(3, 2); If Jim runs 2 minutes, he completes 3 laps.

Answer 1

Question 1: The constant of proportionality from the graph is A, 22.

Question 2: The coordinates of point A are (2, 3). In the context of the problem, this means that if Jim runs for 2 minutes, he completes 3 laps.
