Question

Решите задачу ^0^: ---------------------------------------------------------------------------------------------------------------------------------- Собственная скорость парохода равна 36км/ч, а скорость течения реки - 2,3км/ч. Сначала пароход шел 1,6 часа против течения, а затем 0,6 часа по течению. Найти путь, пройденный пароходом за все время.

Answer 1

36+2,3 = 38,3 км/ч - скорость парохода по течению
36-2,3 = 33,7 км/ч - скорость парохода против течения
1,6*33,7 = 53,92 км - пароход прошел против течения
0,6*38,3 = 22,98 км - пароход прошел по течению
53,92+22,98 = 76,9 км - путь пройденный пароходом за всё время
Ответ: 76,9 км

Answer 2

1)(36-2,3)*1,6=53,92(км) - прошёл против течения
2)(36+2,3)*0,6=22,98(км) - прошёл по течению
3)53,92+22,98=76,9(км) - путь, пройденный пароходом за всё время
Ответ: 76,9 км.

Answer 3

Problem Analysis

To solve this problem, we need to find the total distance traveled by the steamboat. We are given the steamboat's own speed and the speed of the river current. The steamboat travels against the current for 1.6 hours and then travels with the current for 0.6 hours. We need to calculate the total distance traveled by the steamboat during this time.

Solution

To find the total distance traveled by the steamboat, we can use the formula:

Total Distance = Distance Against Current + Distance With Current

Let's calculate each part separately.

Distance Against Current

The distance traveled against the current can be calculated using the formula:

Distance Against Current = Speed of Steamboat * Time Against Current

Given that the speed of the steamboat is 36 km/h and the time against the current is 1.6 hours, we can calculate the distance against the current as follows:

Distance Against Current = 36 km/h * 1.6 hours

Distance With Current

The distance traveled with the current can be calculated using the formula:

Distance With Current = Speed of Steamboat * Time With Current

Given that the speed of the steamboat is 36 km/h and the time with the current is 0.6 hours, we can calculate the distance with the current as follows:

Distance With Current = 36 km/h * 0.6 hours

Total Distance

Now, we can calculate the total distance traveled by the steamboat by adding the distance against the current and the distance with the current:

Total Distance = Distance Against Current + Distance With Current

Let's substitute the values we calculated earlier:

Total Distance = (36 km/h * 1.6 hours) + (36 km/h * 0.6 hours)

Now we can calculate the total distance.

Calculation

Let's calculate the total distance traveled by the steamboat.

Distance Against Current = 36 km/h * 1.6 hours = 57.6 km

Distance With Current = 36 km/h * 0.6 hours = 21.6 km

Total Distance = 57.6 km + 21.6 km = 79.2 km

Therefore, the steamboat traveled a total distance of 79.2 km during the given time.

Answer

The steamboat traveled a total distance of 79.2 km during the given time.
