Final answer:
To find the width of the rectangular park, divide the area by the length using the formula: length x width = area. The width of the park is 24/35 mile.
Step-by-step explanation:
To find the width of the park, we can use the formula for the area of a rectangle: length x width. In this case, the length is given as 7/8 mile and the area is 3/5 square mile. We can let the width be 'w'.
So, we have the equation: (7/8) x w = 3/5. To solve for 'w', we need to isolate it on one side of the equation. We can do this by multiplying both sides of the equation by the reciprocal of (7/8), which is (8/7).
After multiplying, we get w = (8/7) x (3/5) = 24/35 mile. Therefore, the width of the park is 24/35 mile.
