Introduction

Ling wants to determine the average distance she travels each day in her car. To achieve this, she records the odometer reading, which measures the cumulative distance the car has traveled, each morning for a specified period. This problem involves calculating the average distance traveled, which is a fundamental concept in mathematics. In this article, we will explore the steps involved in determining the average distance traveled and provide a mathematical approach to solving this problem.

Understanding the Problem

To determine the average distance traveled, we need to understand the concept of averages. An average is a value that represents the middle or typical value of a set of numbers. In this case, we want to find the average distance traveled by Ling's car over a specified period.

Calculating the Average Distance Traveled

To calculate the average distance traveled, we need to follow these steps:

Record the Odometer Readings: Ling records the odometer reading each morning for a specified period. Let's assume she records the readings for 10 days.
Calculate the Total Distance Traveled: We need to calculate the total distance traveled by subtracting the initial odometer reading from the final odometer reading. Let's assume the initial odometer reading is 100 miles and the final odometer reading is 500 miles. The total distance traveled is 500 - 100 = 400 miles.
Calculate the Average Distance Traveled: To calculate the average distance traveled, we need to divide the total distance traveled by the number of days. In this case, the average distance traveled is 400 miles / 10 days = 40 miles per day.

Mathematical Formula

The mathematical formula to calculate the average distance traveled is:

Average Distance Traveled = (Total Distance Traveled) / (Number of Days)

Example

Let's consider an example to illustrate the calculation of the average distance traveled.

Suppose Ling records the odometer readings for 10 days as follows:

Day	Odometer Reading
1	100 miles
2	120 miles
3	140 miles
4	160 miles
5	180 miles
6	200 miles
7	220 miles
8	240 miles
9	260 miles
10	280 miles

To calculate the average distance traveled, we need to calculate the total distance traveled and divide it by the number of days.

Total Distance Traveled = 280 miles - 100 miles = 180 miles

Average Distance Traveled = 180 miles / 10 days = 18 miles per day

Conclusion

In conclusion, determining the average distance traveled involves recording the odometer readings, calculating the total distance traveled, and dividing it by the number of days. The mathematical formula to calculate the average distance traveled is (Total Distance Traveled) / (Number of Days). By following these steps, we can determine the average distance traveled and gain a better understanding of the concept of averages.

Real-World Applications

The concept of averages has numerous real-world applications. For example, in finance, averages are used to calculate the average return on investment. In medicine, averages are used to calculate the average life expectancy of a population. In sports, averages are used to calculate the average score of a team.

Common Mistakes

When calculating the average distance traveled, there are several common mistakes to avoid:

Not recording the odometer readings: Failing to record the odometer readings can lead to inaccurate calculations.
Not calculating the total distance traveled: Failing to calculate the total distance traveled can lead to incorrect averages.
Not dividing by the correct number of days: Failing to divide by the correct number of days can lead to incorrect averages.

Not dividing by the correct number of days

Q: How do I determine the number of days for the calculation?

A: The number of days for the calculation is the number of days for which you have recorded the odometer readings.

Q: Can I use this method to calculate the average distance traveled for a specific route?

A: Yes, you can use this method to calculate the average distance traveled for a specific route. However, you will need to record the odometer readings at the beginning and end of each route.

Q: How accurate is this method?

A: This method is accurate as long as you record the odometer readings correctly and calculate the total distance traveled accurately.

Q: Can I use this method to calculate the average distance traveled for a vehicle with a different type of odometer?

A: Yes, you can use this method to calculate the average distance traveled for a vehicle with a different type of odometer. However, you may need to adjust the calculation to account for any differences in the odometer readings.

Q: How do I round the average distance traveled to the nearest whole number?

A: To round the average distance traveled to the nearest whole number, you can use the standard rounding rules. For example, if the average distance traveled is 12.5 miles, you would round it to 13 miles.

Q: Can I use this method to calculate the average distance traveled for a vehicle with a variable odometer reading?

A: Yes, you can use this method to calculate the average distance traveled for a vehicle with a variable odometer reading. However, you will need to adjust the calculation to account for any changes in the odometer reading.
