Question

Поезд прошёл 520км. горизонтальный участок пути составляет 4/5 от всего пути, подъём 4% горизонтального участка. Какой процент всего пути составляет подъём?

Answer 1

520*4/5=416 км

4%=0.04

416*0.04 =16,64

Answer 2

Calculation of the Distance Covered on the Incline

To determine the percentage of the total distance covered by the incline, we need to calculate the distance covered on the incline first.

Given: - Total distance traveled by the train: 520 km - Horizontal section of the path: 4/5 of the total distance - Incline of the horizontal section: 4%

To find the distance covered on the incline, we can use the following formula:

Distance on the incline = Total distance * (Percentage of incline / 100)

Substituting the given values into the formula:

Distance on the incline = 520 km * (4% / 100) = 520 km * 0.04 = 20.8 km

Therefore, the distance covered on the incline is 20.8 km.

Calculation of the Percentage of the Total Distance Covered by the Incline

To find the percentage of the total distance covered by the incline, we can use the following formula:

Percentage of the total distance covered by the incline = (Distance on the incline / Total distance) * 100

Substituting the values we calculated earlier:

Percentage of the total distance covered by the incline = (20.8 km / 520 km) * 100 ≈ 4%

Therefore, the incline covers approximately 4% of the total distance traveled by the train.
