Answer :
The average speed of the runner is approximately 19.248 kilometers per hour.
To calculate the average speed of the runner in kilometers per hour, we need to convert the distance from miles to kilometers and the time from hours, minutes, and seconds to hours.
First, let's convert the distance:
1 mile is approximately equal to 1.60934 kilometers.
So, 26.2 miles * 1.60934 kilometers/mile = 42.195 km (rounded to 3 decimal places).
Next, let's convert the time:
2 hours + (11 minutes / 60) + (29 seconds / 3600) = 2.191388889 hours (rounded to 9 decimal places).
Finally, we can calculate the average speed:
Average Speed = Distance / Time
Average Speed = 42.195 km / 2.191388889 hours
Average Speed ≈ 19.248 km/h (rounded to 3 decimal places).
