Answer
The 40-meter race begins and the biker starts peddling. In the first 10 seconds, they cover 10 meters at a constant pace. Then, the biker speeds up and covers another 30 meters in 10 seconds. After crossing the 40-meter line the bike comes to a quick stop.
Work Step by Step
The first line from 0 seconds to 10 seconds depicts a movement of 10 meters. The second line from 10 seconds to 20 seconds, is slanted more and covers a distance of 30 meters (y-axis). Between 20 seconds and 30 seconds, there is no change in distance as shown with the horizontal line.
