Question

each point on the coordinate plane represents the time, in minutes, it took jim to jog different distances, in miles.

chart: distances jogged with x-axis time (minutes) (0 - 50) and y-axis distance (miles) (0 - 10). points at (20,2), (30,3), (40,4).

based on the data graphed, what distance did jim jog in 30 minutes?

a. 4 miles
b. 2 miles
c. 3 miles
d. 2.5 miles

Explanation:

To determine the distance Jim jogged in 30 minutes, we look at the coordinate plane. The x - axis represents time (in minutes) and the y - axis represents distance (in miles). We find the point where the time (x - value) is 30 minutes. From the graph, the point corresponding to 30 minutes on the x - axis has a y - value (distance) of 3 miles? Wait, no, let's re - check. Wait, looking at the points: at 20 minutes, distance is 2 miles; at 30 minutes, the point is at y = 3? Wait, no, the options: A is 4, B is 2, C is 3, D is 2.5. Wait, let's look at the graph again. The points: when x = 20, y = 2; x = 30, y = 3? Wait, no, maybe I misread. Wait, the graph has points: (20, 2), (30, 3), (40, 4)? Wait, no, the y - axis is distance (miles) with 0, 2, 4, 6, 8, 10. The x - axis is time (minutes) 0, 10, 20, 30, 40, 50. So the point at x = 30 (time = 30 minutes) has a y - coordinate (distance) of 3 miles? Wait, but let's check the options. Option C is 3 miles. Wait, but maybe I made a mistake. Wait, no, let's see: if at 20 minutes, distance is 2 miles (so rate is 2/20 = 0.1 miles per minute). Then in 30 minutes, distance would be 0.1*30 = 3 miles. So the correct option is C.

Answer:

C. 3 miles
