Answer: 20 steps
Step-by-step explanation:
From the question, we are informed that the average person's stride length the distance covered by one step is 2.5 feet long.
To know the steps that the average person would take to travel 50 feet, we simply have to divide 50 feet by 2.5 feet. This will be:

= 20
This means that an individual will take 20 steps to travel 50 feet
