Answer 1

To compare Pete's motion during the first 10 minutes and the last 10 minutes of his trip, we can analyze the characteristics of his journey as described in your question. The following observations can be made:

1. Direction of Motion: If Pete is indeed traveling in a different direction during the last 10 minutes compared to the first 10 minutes, that would imply a change in direction.

2. Speed and Acceleration: It should be noted if he is speeding up or slowing down in those respective segments. If the distance he is covering is increasing at a higher rate in the first 10 minutes compared to the last, that would indicate he is accelerating at different rates.

Options for comparison:

• "He is going faster and in a different direction during the first 10 minutes than in the last 10 minutes."
• "His acceleration increases during the first 10 minutes and decreases during the last 10 minutes."
• "He is going slower and in a different direction during the first 10 minutes than in the last 10 minutes."
• "He is speeding up during the first 10 minutes and slowing down during the last 10 minutes."

Based on these options, the safest conclusion would revolve around the identified distinctions in speed and potential acceleration changes, such as “He is speeding up during the first 10 minutes and slowing down during the last 10 minutes,” assuming the distance graph shows an increase in distance at a higher rate initially and a decrease in rate later on.

Without specific details on the actual graph that plots distance against time, one can’t pinpoint the exact comparison. However, select the answer that aligns best with the details in the graph.
