Question

На одной прямой через равные промежутки по одну сторону сторону от дороги установили три столба. крайний находится на рассиояниях 6,7 и 7,9метров от дороги. найдите расстояния на котором находится от дороги средний столб. ответ дайте в метрах

Answer 1

6,7+2х=7,9
2х=7,9-6,7
2х=1,2
х=1,2/2
х=0,6 - расстояние через которое установлены столбы
средний-6,7+0,6=7,3 метра

Answer 2

The Problem

Three poles are placed at equal distances along one side of a road. The outer poles are 6.7 meters and 7.9 meters from the road. We need to find the distance of the middle pole from the road.

Breaking Down the Information

Three poles are placed along one side of a road. The distances of the outer poles from the road are 6.7 meters and 7.9 meters. We need to find the distance of the middle pole from the road.

Developing a Plan

Since the poles are placed at equal distances, we can set up an equation relating the distances. Let x = the distance of the middle pole from the road. Then the distances will be: 6.7, x, 7.9

Solving the Equation

We know: 6.7 + x + 7.9 = 3d Where d is the equal distance between poles 6.7 + x + 7.9 = 3d 14.6 + x = 3d 3d - 14.6 = x x = 7.3 meters

Answer

Therefore, the distance of the middle pole from the road is 7.3 meters.
