Final answer:
The average speed for a trip of 6 kilometers in 12 minutes is calculated by dividing the total distance by the total time, which results in an average speed of 0.5 kilometers per minute (Option A).
Step-by-step explanation:
To calculate the average speed of a trip, you divide the total distance traveled by the total time taken for the trip. In this case, you need to find the average speed of a car traveling a distance of 6 kilometers in a time span of 12 minutes. Since speed is typically measured in kilometers per hour (km/h), we can convert the time from minutes to hours to find the average speed in standard units.
First, convert 12 minutes to hours:
- 12 minutes × (1 hour / 60 minutes) = 0.2 hours
Then, use the formula for average speed:
- Average speed = Total distance / Total time
- Average speed = 6 km / 0.2 hours
- Average speed = 30 km/h
To find the answer in km/min, we divide the 6 km by 12 minutes directly:
- Average speed = 6 km / 12 min
- Average speed = 0.5 km/min
Therefore, the correct answer is Option A, 0.5 km/min.
