Final answer:
The sparrow was faster than the hawk.
Step-by-step explanation:
To determine which bird is faster, we need to compare their speeds. The formula for speed is distance divided by time. The hawk flew 600 meters in 1 minute, so its speed is 600/1 = 600 meters per minute. The sparrow flew 400 meters in 30 seconds, so its speed is 400/0.5 = 800 meters per minute. Comparing the speeds, we can see that the sparrow was faster than the hawk.
