Question

Три туриста прошли вместе 1992 км . Первый был в пути 12 дней, второй - 18, третий - 30 дней. Первый турист за 4 дня прошел столько , сколько второй за 5 дней, а третий - за 6 дней столько, сколько второй за 10 . Сколько километров прошел каждый турист? Помогите пожалуйста Можно решения этой задачи Спасибо!

Answer 1

Узнаем сколько прошел каждый за один день:
1)1992:12=166(км)1й турист за один день
2)1992:18=110,7 если округлить то 111 (км)-2й турист за один день
3)1992:30=66,4 или просто 66 (км)-3й турист за один день
Далее,узнаем сколько 1й турист прошёл за 4 дня:
111км *5 =555 (км)1й турист за 4 дня,2й турист за 5 дней
111 км*10дней=1110 (км)2й турист за 10 дней,3й за 6 дней

Думаю ,что так

Answer 2

Problem Analysis

We are given that three tourists walked a total distance of 1992 km together. The first tourist took 12 days, the second took 18 days, and the third took 30 days to complete the journey. We are also given additional information about the distances covered by each tourist in specific time periods. We need to find the distance covered by each tourist.

Solution

Let's assume the distances covered by the first, second, and third tourists are x, y, and z kilometers, respectively.

From the given information, we can form the following equations:

1. The sum of the distances covered by all three tourists is 1992 km: x + y + z = 1992 2. The first tourist covered the same distance in 4 days as the second tourist covered in 5 days: x/4 = y/5 3. The third tourist covered the same distance in 6 days as the second tourist covered in 10 days: z/6 = y/10 To solve these equations, we can use substitution or elimination methods. Let's use the substitution method.

From equation we can express x in terms of y: x = (4/5)y

Substituting this value of x in equation we get: (4/5)y/6 = y/10 (4/5) * (10/6) * y = y (4/3)y = y 4y = 3y y = 0

This implies that the second tourist did not cover any distance, which is not possible. Therefore, there is no solution to this problem.

Conclusion

Based on the given information, it is not possible to determine the distances covered by each tourist.
