Answer: The distance from the school to the park = 9 miles.
Step-by-step explanation:
Given: The distance from the school to the library is 12 miles.
The distance from the school to the park is 75% of this distance.
The distance from the school to the park = 75% of (distance from the school to the library)
= 0.75 × (12 miles)
= 9 miles
Hence, the distance from the school to the park = 9 miles.
