1. 5 kilometers per hour was Kosi's speed at the 5 kilometer mark in the race.
2. According to the graph, near 8 kilometer mark was Kosi when he was going the slowest during the race.
The graph shows Kori's speed during a 10 kilometer race. The x-axis of the graph represents the distance (in kilometers) that Kori has run, and the y-axis represents Kori's speed (in kilometers per hour). The line on the graph shows how Kori's speed changes throughout the race.
Kori starts the race at a speed of 10 kilometers per hour. He gradually slows down throughout the race, reaching his slowest speed of 5 kilometers per hour at the 8 kilometer mark.
After the 8 kilometer mark, Kori picks up speed and finishes the race at a speed of 10 kilometers per hour.
question 1
Kori's speed at the 5 kilometer mark in the race is 5 kilometers per hour. This can be seen by following the 5 kilometer mark on the x-axis of the graph up to the line. The line intersects the y-axis at 5 kilometers per hour.
5 kilometers per hour
question 2
Kori is going the slowest during the race at the 8 kilometer mark. This can be seen by following the line on the graph from left to right. The line reaches its lowest point at the 8 kilometer mark, which indicates that Kori is going the slowest at this point.
