Introduction

Cross-country skiing is a popular winter sport that requires endurance, strength, and technique. In this article, we will explore the concept of rate of change in the context of Carol's cross-country skiing adventure. We will examine a table that shows the distance she traveled after various numbers of minutes and determine the rate of change.

What is Rate of Change?

Rate of change is a fundamental concept in mathematics that refers to the change in a quantity over a given period of time. It is a measure of how fast something is changing. In the context of Carol's cross-country skiing adventure, the rate of change represents the speed at which she is traveling.

The Table: Distance Carol Traveled

Time (minutes) Distance (meters)
0 0
5 50
10 120
15 220
20 320
25 420
30 520

Calculating the Rate of Change

To calculate the rate of change, we need to find the difference in distance traveled over a given period of time. Let's examine the table and calculate the rate of change for each time interval.

  • From 0 to 5 minutes, the distance traveled is 50 meters. The rate of change is 50 meters / 5 minutes = 10 meters per minute.
  • From 5 to 10 minutes, the distance traveled is 70 meters. The rate of change is 70 meters / 5 minutes = 14 meters per minute.
  • From 10 to 15 minutes, the distance traveled is 100 meters. The rate of change is 100 meters / 5 minutes = 20 meters per minute.
  • From 15 to 20 minutes, the distance traveled is 100 meters. The rate of change is 100 meters / 5 minutes = 20 meters per minute.
  • From 20 to 25 minutes, the distance traveled is 100 meters. The rate of change is 100 meters / 5 minutes = 20 meters per minute.
  • From 25 to 30 minutes, the distance traveled is 100 meters. The rate of change is 100 meters / 5 minutes = 20 meters per minute.

Analyzing the Results

From the calculations above, we can see that the rate of change is increasing over time. The initial rate of change is 10 meters per minute, and it increases to 20 meters per minute after 20 minutes. This suggests that Carol's speed is increasing over time.

Conclusion

In conclusion, the rate of change in Carol's cross-country skiing adventure represents the speed at which she is traveling. By analyzing the table and calculating the rate of change for each time interval, we can see that the rate of change is increasing over time. This suggests that Carol's speed is increasing over time, which is consistent with the demands of cross-country skiing.
