Final answer:
The average speed of the person walking is 6.25 feet per second.
Step-by-step explanation:
To calculate the speed at which a person is walking, we need to divide the distance traveled by the time taken. In this case, the person walks 3,000 feet in 8 minutes.
To convert the time to seconds, we multiply it by 60 since there are 60 seconds in a minute. So, the person walks 3,000 feet in 480 seconds. The average speed can be calculated by dividing the distance (in feet) by the time (in seconds).
Average Speed = Distance / Time
So, the average speed of the person walking would be 3,000 feet / 480 seconds = 6.25 feet per second.
