Answer:
The person has a higher average speed, so the person moves faster than the bird.
Step-by-step explanation:
We have to work with the measures in the same units, i am going to use distance in kilometers and time in minutes.
A certain species of birds migrates 24,000 miles in 90 days.
24000 miles = 24000*1.61 = 38640 kilometers.
90 days = 90*24*60 minutes = 129 600 minutes.
Average speed is distance divided by time, so
38640/129600 = 0.298 kilometers per minute.
A person can speed walk 40 kilometers in 100 minutes.
40/100 = 0.4 kilometers per minute
0.4 > 0.298, so the person moves faster.
