What is the average speed of a runner who covers 5 km in 25 minutes?
To find the average speed, we can use the formula: Average Speed = Distance / Time.
In this case, the distance covered is 5 km and the time taken is 25 minutes.
Average Speed = 5 km / 25 minutes
To convert the time to hours, divide by 60 (minutes in an hour):
Average Speed = 5 km / (25 minutes / 60 minutes per hour)
Average Speed = 5 km / (25/60) hour
Average Speed = 5 km / (5/12) hour
Average Speed = 5 km * (12/5) hour
Average Speed = 12 km/hour
Therefore, the average speed of the runner is 12 km/hour.
