Question

Помогите, пожалуйста! На участке дороги длиной 320м одинаковый подъем. На концах участка стоят обозначения: 186,5 м и 194,9 м Какое обозначение должно быть на расстоянии 120 м от начала подъёма?

Answer 1

(194,9 - 186,5)÷32 = 0,2625 Тогда за 120м высота увеличится на 0,2625*12= 3,15м. Следовательно искомая отметка равна 186,5+3,15 = 189,65м

Answer 2

Calculation of the Elevation at a Specific Distance

To determine the elevation at a specific distance from the beginning of the incline, we can use the concept of proportionality.

Given: - Length of the road segment: 320m - Elevation at one end of the segment: 186.5m - Elevation at the other end of the segment: 194.9m

We can set up a proportion to find the elevation at a distance of 120m from the beginning of the incline:

Elevation at 120m / Length of segment = Elevation at one end / Length of segment

Let's solve this proportion to find the elevation at 120m from the beginning of the incline.

Calculation:

Elevation at 120m = (Elevation at one end / Length of segment) * Length at 120m

Elevation at 120m = (186.5m / 320m) * 120m

Elevation at 120m = (0.5828125) * 120m

Elevation at 120m ≈ 69.9375m

Therefore, the elevation at a distance of 120m from the beginning of the incline should be approximately 69.94m.

Please note that the above calculation assumes a linear relationship between distance and elevation. If there are any other factors or variations in the incline, the result may differ.
