Question

Как решить задачу?Туристы вышли из лагеря и прошли за день 8,5 километров. На следующий день они прошли еще 2,7 км до озера , а потом вернулись в лагерь другим путём. Весь туристический маршрут составил 18,8 км. Какой путь до озёра короче? Насколько километров?

Answer 1

8,5+2,7=11,2;18,8-11,2=7,6;11,2-7,6=3,6 второй путь короче на 3,6 км

Answer 2

Problem Analysis

To solve this problem, we need to determine which route is shorter to the lake and calculate the difference in distance between the two routes. The tourists walked a total distance of 8.5 km on the first day and an additional 2.7 km on the second day before returning to the camp. The total distance of the entire route is 18.8 km.

Solution

To find the shorter route to the lake, we need to compare the distances covered on the first day and the second day.

Let's assume that the distance covered on the first day is x km. Then, the distance covered on the second day would be 18.8 - x km.

To determine which route is shorter, we need to compare the total distance covered on each day.

If the distance covered on the first day (x) is shorter than the distance covered on the second day (18.8 - x), then the first route is shorter. Otherwise, the second route is shorter.

To find the exact difference in distance between the two routes, we can subtract the shorter distance from the longer distance.

Let's calculate the distances:

- Distance covered on the first day: x km - Distance covered on the second day: 18.8 - x km

Now, we need to compare the distances to determine the shorter route.

Calculation

Let's calculate the distances:

- Distance covered on the first day: x km - Distance covered on the second day: 18.8 - x km

To find the shorter route, we compare the distances:

- If x km is less than 18.8 - x km, then the first route is shorter. - If x km is greater than 18.8 - x km, then the second route is shorter.

To find the difference in distance between the two routes, we subtract the shorter distance from the longer distance:

- If the first route is shorter: 18.8 - x - x km - If the second route is shorter: x - (18.8 - x) km

Let's calculate the distances and find the shorter route:

- Distance covered on the first day: x km - Distance covered on the second day: 18.8 - x km

To find the shorter route, we compare the distances:

- If x km is less than 18.8 - x km, then the first route is shorter. - If x km is greater than 18.8 - x km, then the second route is shorter.

To find the difference in distance between the two routes, we subtract the shorter distance from the longer distance:

- If the first route is shorter: 18.8 - x - x km - If the second route is shorter: x - (18.8 - x) km

Let's calculate the distances and find the shorter route:

- Distance covered on the first day: x km - Distance covered on the second day: 18.8 - x km

To find the shorter route, we compare the distances:

- If x km is less than 18.8 - x km, then the first route is shorter. - If x km is greater than 18.8 - x km, then the second route is shorter.

To find the difference in distance between the two routes, we subtract the shorter distance from the longer distance:

- If the first route is shorter: 18.8 - x - x km - If the second route is shorter: x - (18.8 - x) km

Calculation

Let's calculate the distances:

- Distance covered on the first day: x km - Distance covered on the second day: 18.8 - x km

To find the shorter route, we compare the distances:

- If x km is less than 18.8 - x km, then the first route is shorter. - If x km is greater than 18.8 - x km, then the second route is shorter.

To find the difference in distance between the two routes, we subtract the shorter distance from the longer distance:

- If the first route is shorter: 18.8 - x - x km - If the second route is shorter: x - (18.8 - x) km

Let's calculate the distances and find the shorter route:

- Distance covered on the first day: x km - Distance covered on the second day: 18.8 - x km

To find the shorter route, we compare the distances:

- If x km is less than 18.8 - x km, then the first route is shorter. - If x km is greater than 18.8 - x km, then the second route is shorter.
