Question

3п три для туристи пройшли 38 км. За другий день вони пройшли у 2 рази більше ніж за перший, а за третій на 6 км більше, ніж перший. Скільки кілометрів пройшли туристи за кожний день?

Answer 1

Ответ:

Пошаговое объяснение:

1 д = х

2 д = 2х

3 д = х + 6

х + 2х + х + 6 = 38

х + 2х + х = 38 - 6

4х = 32

х = 8

1 д = 8 км

2 д = 2 * 8 = 16 км

3 д = 8 + 6 = 14 км

Answer 2

Problem Analysis

We are given that a group of tourists walked a total of 38 km over 3 days. On the second day, they walked twice as much as on the first day, and on the third day, they walked 6 km more than on the first day. We need to determine how many kilometers the tourists walked each day.

Solution

Let's assume that the number of kilometers walked on the first day is represented by x.

According to the given information: - On the second day, they walked twice as much as on the first day, so the distance walked on the second day is 2x. - On the third day, they walked 6 km more than on the first day, so the distance walked on the third day is x + 6.

The total distance walked over the three days is 38 km. Therefore, we can write the equation:

x + 2x + (x + 6) = 38

Simplifying the equation: 4x + 6 = 38

Subtracting 6 from both sides: 4x = 32

Dividing both sides by 4: x = 8

Therefore, the tourists walked 8 km on the first day, 16 km on the second day, and 14 km on the third day.

Answer

The tourists walked 8 km on the first day, 16 km on the second day, and 14 km on the third day.
