Final answer:
Peter walked approximately 1.5 miles to the nearest tenth of a mile.
Step-by-step explanation:
To find the distance Peter walked to the nearest tenth of a mile, we need to convert the given distance in feet to miles. We know that 1 mile is equal to 5,280 feet. So, we can set up a proportion to solve for the distance in miles:
8,000ft / 5,280ft = x miles
Cross multiplying, we get:
8,000ft * 1 mile = 5,280ft * x miles
x = (8,000ft * 1 mile) / 5,280ft
x = 1.5152 miles
Therefore, Peter walked approximately 1.5 miles to the nearest tenth of a mile.
