2. Sketch a distance-time graph of the situation explained below in the blank coordinate
grid.
A person begins to run and travels 30 meters in the first 10 seconds of his trip. He then decides
to stop because running for 10 seconds was way too difficult. He only rests for 5 seconds. He
then runs with a velocity of 2 m/s for 10 more seconds. He then turns around and jogs back to
his original position, at a non-constant rate of change, arriving there at t=30 seconds.
