which best describes his run?\nfrom time 0 to 6, he went fast and then slowed down.\nfrom time 6 to 10, he was at his slowest.\nfrom time 12 to 14, he went very slow.\nfrom time 14 to 18, he went toward the starting point.
Answer
Explanation:
Step1: Analyze slope for speed
The slope of a position - time graph represents speed. Steeper slope means higher speed.
Step2: Analyze option 1
From 0 - 4, slope is steeper, from 4 - 6 slope is less steep, so speed decreases, but not exactly as described in option 1.
Step3: Analyze option 2
From 6 - 10, the slope is non - zero and not the smallest among all intervals, so not the slowest.
Step4: Analyze option 3
From 12 - 14, the slope is close to zero, indicating very slow movement.
Step5: Analyze option 4
From 14 - 18, the position is increasing, so moving away from starting point.
Answer:
From time 12 to 14, he went very slow.
