Question

Jaques ran a cross-country meet after school. After 3.5 minutes, he was 630 m from the starting line. After 7.0 minutes, he was 1260 m from the starting line. What was Jaques' velocity during that segment of the race?​

Answer 1

Jacques' velocity during the segment of the cross-country meet was calculated to be 3 m/s by dividing the displacement of 630 meters by the time taken of 210 seconds.

Step-by-step explanation:

The student is asking about the calculation of velocity during a cross-country race. To find Jacques' velocity, we need to use the formula for velocity, which is the displacement divided by the time taken. In this case, Jacques was 630 m from the starting line after 3.5 minutes and 1260 m after 7.0 minutes. Therefore, his displacement during the segment in question is 1260 m - 630 m = 630 m. The time taken for this segment is 7.0 minutes - 3.5 minutes = 3.5 minutes. To find the velocity in meters per second (m/s), we convert the time from minutes to seconds and then divide the displacement by time.

Here's the calculation:

• Time in seconds: 3.5 minutes × 60 seconds/minute = 210 seconds
• Velocity: 630 m / 210 s = 3 m/s

Jacques' velocity during this segment of the cross-country meet was 3 m/s.
