Calculating Average Pace and Speed in a 10K Run

Running a 10 kilometer race is a popular fitness goal for many runners. If you completed a 10 kilometer race in 42 minutes and 42 seconds, how would you calculate your average pace and speed in both kilometers and miles? This article will walk you through the steps to find the average pace per kilometer and mile, as well as the average speed in miles per hour.

Calculating Average Pace

To calculate the average pace, we need to divide the total time taken by the total distance covered. Let's break this down step by step.

Total Time and Distance

Total time taken: 42 minutes and 42 seconds 42.7 minutes

Total distance covered: 10 kilometers

Average pace per kilometer is calculated as follows:

[ text{Average pace per kilometer} frac{text{Total time taken}}{text{Total distance covered}} frac{42.7 text{ minutes}}{10 text{ kilometers}} approx 4.27 text{ minutes per kilometer} ]

This means the average pace is approximately 4 minutes and 16 seconds per kilometer (0.27 minutes ≈ 16 seconds).

Converting Pace to Miles

To convert the pace to minutes per mile, we need to account for the conversion factor between kilometers and miles. 1 mile is approximately 1.60934 kilometers.

[ text{Average pace per mile} frac{text{Average pace per kilometer}}{1.60934} frac{4.27 text{ minutes}}{1.60934} approx 2.65 text{ minutes per mile} ]

In terms of minutes and seconds, 0.65 minutes 39 seconds.

Therefore, the average pace is approximately 2 minutes and 39 seconds per mile.

Calculating Average Speed in Miles Per Hour

To calculate the average speed in miles per hour, we first need to convert the total time taken to hours.

Time Conversion

Total time taken 42.7 minutes 42.7/60 hours ≈ 0.712 hours

Average speed is then calculated as:

[ text{Average speed} frac{text{Total distance covered}}{text{Total time taken in hours}} frac{10 text{ kilometers}}{0.712 text{ hours}} approx 14.04 text{ kilometers per hour} ]

Converting this speed to miles per hour, given that 1 kilometer is approximately 0.621371 miles:

[ text{Average speed in miles per hour} frac{14.04 text{ kilometers per hour}}{0.621371} approx 22.59 text{ miles per hour} ]

This means the average speed is approximately 22.59 miles per hour.
