Answer:
See below
Step-by-step explanation:
This graph could describe a relay race.
Jamie writes a scenario that can be modeled by the piecewise function on the graph.
The graph has time, in minutes on the x-axis and the distance, in miles on the y-axis.
The first part of the graph is the line starting from the origin through to the point (12, 1) then the second part starts from the point (12, 1) and ends on the point (20, 2).
1. A runner begins the race and runs at a steady pace for 1 minute.
It should say: a runner begins a race and runs at a steady pace for 12 minutes, completing 1 mile distance.
<u>The equation for this part:</u>
2. His partner then takes over and runs at a steady, but faster, pace for another 1 minute.
It should say: his partner then takes over and runs at a steady, but faster, pace for another 8 minutes, completing the last 1 mile of the race.
<u>The equation for this part:</u>
