Final answer:
The average speed for the distances provided is calculated by dividing the total distance by the total time. The total distance is 3 km, and the total time is 38 minutes, resulting in an average speed of approximately 0.079 km/minute.
Step-by-step explanation:
To determine the average speed in minutes for the distances provided, we need to calculate the speed for each distance and then find the overall average. Speed is the distance traveled divided by the time taken, and average speed is the total distance divided by the total time for all segments.
From the question we have the following speeds:
- 2 km in 22 minutes
- 1 km in 16 minutes
We will calculate the average speed as follows:
- Find the total distance travelled.
- Find the total time taken.
- Calculate the average speed by dividing the total distance by the total time.
The total distance is 2 km + 1 km = 3 km. The total time is 22 minutes + 16 minutes = 38 minutes.
Now, let's calculate the average speed:
- Total distance = 3 km
- Total time = 38 minutes
- Average speed = Total distance / Total time
- = 3 km / 38 minutes
To get the speed in km/minute, divide the kilometres by minutes:
Average speed = 3 km / 38 minutes
≈ 0.079 km/minute
Note that to convert this speed into km/h, one would have to multiply it by 60, since there are 60 minutes in an hour.
