1. Problem Description

The problem states that the distance dd between two villages is more than 18 km but not more than 23 km. We need to choose the inequality that represents this statement.

2. Solution Steps

The statement "more than 18 km" means d>18d > 18 or 18<d18 < d.
The statement "not more than 23 km" means d≤23d \le 23.
Combining these two inequalities, we have 18<d≤2318 < d \le 23.

3. Final Answer

D. 18<d≤2318 < d \le 23
