Question

Туристы прошли за три дня 48 км: в первый день - 1/2 всего расстояния, а во второй день - 1/3 того расстояния, что они прошли в первый день. Сколько км они прошли в третий день?Помогите, очень надо!!!

Answer 1

Всего за три дня 48 км
1/2*48=24 в первый день
1/3*24=6 rv во второй день
48-24-6=18 км в третий день

Answer 2

Problem Analysis

The problem states that a group of tourists walked a total distance of 48 km in three days. On the first day, they walked half of the total distance, and on the second day, they walked one-third of the distance they covered on the first day. The question is asking how many kilometers they walked on the third day.

Solution

To solve this problem, we need to calculate the distances walked on each day.

Let's denote the distance walked on the first day as x km. According to the problem, the distance walked on the second day is one-third of the distance walked on the first day, which is x/3 km.

We know that the total distance covered in three days is 48 km. So, we can set up the following equation:

x + x/3 + ? = 48

To find the distance walked on the third day, we need to solve for the missing value in the equation.

Calculation

To solve the equation, we can simplify it by combining like terms:

4x/3 + ? = 48

To isolate the missing value, we can subtract 4x/3 from both sides of the equation:

? = 48 - 4x/3

Now, we need to find the value of x to calculate the distance walked on the third day.

From the problem statement, we know that the distance walked on the first day is half of the total distance, which is 48 km. So, we can set up the following equation:

x = 48/2

Simplifying this equation, we find:

x = 24

Now, we can substitute the value of x into the equation for the missing value:

? = 48 - 4(24)/3

Simplifying further, we get:

? = 48 - 96/3

? = 48 - 32

? = 16

Therefore, the tourists walked 16 km on the third day.

Answer

The tourists walked 16 km on the third day.

Explanation

The total distance covered by the tourists in three days was 48 km. On the first day, they walked half of the total distance, which is 24 km. On the second day, they walked one-third of the distance they covered on the first day, which is 24/3 = 8 km. Finally, on the third day, they walked the remaining distance, which is 16 km.
