Final answer:
Traveling 32.4 miles in 9 hours results in an average speed of 3.6 mph. This calculation is an example of using distance and time to find speed, similar to how one calculates marathon times or a runner's total distance with significant figures.
Step-by-step explanation:
To determine the speed of traveling 32.4 miles in 9 hours, you would use the formula for average speed, which is the total distance divided by the total time. By applying this formula, we find the average speed to be 3.6 miles per hour (mph), as calculated by dividing 32.4 miles by 9 hours. Here are other related examples that illustrate calculations of distance, speed, and time:
- If a marathon runner averages 9.5 mi/h, they would complete a 26.22 mi marathon in approximately 2 hours and 46 minutes.
- A marathon runner's completion of a 42.188 km course in 2 hours, 30 minutes, and 12 seconds has an accuracy influenced by the uncertainty of the distance and time.
- Adding up the different segments of a marathon runner's path, comprising of 9.5 miles, 8.89 miles, and 2.333 miles, gives us a total distance of 20.72 miles, using the appropriate number of significant figures.
These examples help you check the reasonableness of your results by comparing them to other known values, ensuring the right units, and using proper significant figures.
