To determine how much shorter the walk through the park is, we need to calculate the distance of both routes using the Pythagorean Theorem.
The distance of walking straight down Johnson Avenue and then straight down 41st Street can be calculated using the Pythagorean Theorem:
d = √(80^2 + 60^2)
d = √(6400 + 3600)
d = √10000
d = 100 yards
Now, let's calculate the distance of walking through the park. Since the street intersections are at 90° angles, we can use the Pythagorean Theorem again to determine the distance:
d = √(80^2 + 60^2)
d = √(6400 + 3600)
d = √10000
d = 100 yards
The distance of walking through the park is also 100 yards.
Therefore, if Sylvia walks through the park instead of straight down Johnson Avenue and straight down 41st Street, the walk will be 0 yards shorter.
