Question

Геологи мали дістатись до табору. Шлях лісом становив 0,2 усього шляху, відстань, яку вони мали пройти гірською 0,4 того, що залишилось пройти після виходу з лісу, а переправа річкою 0,25 нової остачі. Після переправи до табору залишилось пройти 88,2 км. Який весь шлях? ​

Answer 1

Пошаговое объяснение:

1)0,2-0,4=-0,2

2)-0,2+0,25=0,05

3)0,05+88,2=88,25(км)

Відповідь:88,25 км шляху треба пройти геологам до табору.

Answer 2

To find the total distance of the entire journey, we need to add up the distances traveled through the forest, the mountains, and the river crossing.

Let's break down the information given:

- The distance traveled through the forest is 0.2 of the total distance. - The distance traveled through the mountains is 0.4 of the remaining distance after exiting the forest. - The distance of the river crossing is 0.25 of the new remaining distance after the mountains. - After the river crossing, there is still 88.2 km left to reach the camp.

To calculate the total distance, we can follow these steps:

1. Calculate the distance traveled through the forest: - Distance through the forest = 0.2 * Total distance

2. Calculate the distance traveled through the mountains: - Remaining distance after the forest = Total distance - Distance through the forest - Distance through the mountains = 0.4 * Remaining distance after the forest

3. Calculate the distance of the river crossing: - Remaining distance after the mountains = Remaining distance after the forest - Distance through the mountains - Distance of the river crossing = 0.25 * Remaining distance after the mountains

4. Calculate the total distance: - Total distance = Distance through the forest + Distance through the mountains + Distance of the river crossing + Remaining distance after the river crossing

Let's plug in the given values and calculate the total distance:

1. Distance through the forest: - Distance through the forest = 0.2 * Total distance

2. Distance through the mountains: - Remaining distance after the forest = Total distance - Distance through the forest - Distance through the mountains = 0.4 * Remaining distance after the forest

3. Distance of the river crossing: - Remaining distance after the mountains = Remaining distance after the forest - Distance through the mountains - Distance of the river crossing = 0.25 * Remaining distance after the mountains

4. Total distance: - Total distance = Distance through the forest + Distance through the mountains + Distance of the river crossing + Remaining distance after the river crossing

Let's calculate the total distance using the given information:

1. Distance through the forest: - Distance through the forest = 0.2 * Total distance = 0.2 * X

2. Distance through the mountains: - Remaining distance after the forest = Total distance - Distance through the forest = X - 0.2X = 0.8X - Distance through the mountains = 0.4 * Remaining distance after the forest = 0.4 * 0.8X = 0.32X

3. Distance of the river crossing: - Remaining distance after the mountains = Remaining distance after the forest - Distance through the mountains = 0.8X - 0.32X = 0.48X - Distance of the river crossing = 0.25 * Remaining distance after the mountains = 0.25 * 0.48X = 0.12X

4. Total distance: - Total distance = Distance through the forest + Distance through the mountains + Distance of the river crossing + Remaining distance after the river crossing - Total distance = 0.2X + 0.32X + 0.12X + 88.2 km

Now we can solve for X, which represents the total distance:

0.2X + 0.32X + 0.12X + 88.2 = X

Simplifying the equation:

0.64X + 88.2 = X

Rearranging the equation:

0.36X = 88.2

Dividing both sides by 0.36:

X = 88.2 / 0.36

Calculating the value of X:

X ≈ 245 km

Therefore, the total distance of the entire journey is approximately 245 km.
