Answer 2

Problem Analysis

We are given that there are 5 houses along a straight road, with a distance of 10 meters between each house. The well is located at the middle house. We need to determine the distance between the first house and the well.

Solution

To find the distance between the first house and the well, we need to calculate the total distance from the first house to the middle house. Since there are 5 houses and the distance between each house is 10 meters, the total distance from the first house to the middle house is (5-1) * 10/2 = 20 meters.

Therefore, the well is located 20 meters from the first house.

Answer

The well is located 20 meters from the first house.
