Final answer:
To find the bird's average speed in meters per second, convert 6 km to 6000 meters and divide by 400 seconds, resulting in an average speed of 15 m/s.
Step-by-step explanation:
To calculate the average speed of the bird in meters per second, you need to know the formula for average speed, which is total distance divided by total time.
First, we need to convert the distance from kilometers to meters.
Since there are 1000 meters in one kilometer, 6 km is equal to 6000 meters.
Next, we need to use the given time of 400 seconds.
The formula for calculating average speed is:
Average speed = Total distance / Total time
Substituting the known values gives us:
Average speed = 6000 meters / 400 seconds
= 15 m/s
Therefore, the bird's average speed is 15 meters per second.
