Answer: Tavion is traveling faster than Jonathan, but Tavion is slowing down slightly.
Their initial speeds are:
Jonathan 0.667 miles per minute.
Tavion 0.833 miles per minute.
Step-by-step explanation: To find their speed, divide miles by minutes.
From the graph pick coordinates. (3,2) or (6,4) The y-values are miles, x-values are minutes.
Jonathan: 2 miles ÷ 3 minutes = 0.667 miles per minute.
For Tavion, get his initial speed from the first values in the chart.
Tavion: 12.5 miles ÷ 15 minutes = 0.833 miles per minute.
The miles do not increase exactly as the time increased. They would be 12.5, 25 and 37.5 if his initial speed remained the same.
