Question

Коротышки из цветочного города отправились в поход. В первый день они прошли 940 метров, а во второй день - в 2 раза меньше, чем в первый, и на 120 метров меньше, чем за 3. Какое расстояние прошли коротышки за эти три дня? Ответ выразить в километрах.

Answer 1

Третий день - на 120М больше чем во второй, который в свою очередь 1/2 от первого 940, то есть 470, то есть третий день 470+120=590
Не напрягались мальенькие человечки у Носова - за 3 дня прошли
940+470+590=2км
или так сумма Х = (940+940/2 +940/2+120)/1000=2

Answer 2

1)940/2=470(М)ПРОШЛИ КОРОТЫШКИ ВО ВТОРОЙ ДЕНЬ
2)470+120=590(М)ПРОШЛИ КОРОТЫШКИ В ТРЕТИЙ ДЕНЬ
3)940+470+590=2000(М)ПОШЛИ КОРОТЫШКИ ЗА ТРИ ДНЯ
2000М=2КМ
ОТВЕТ:2 КИЛОМЕТРА ПРОШЛИ КОРОТЫШКИ

Answer 3

Problem Analysis

The problem states that the "Korotyshki" from the "Flower City" went on a hike. On the first day, they walked 940 meters, and on the second day, they walked half as much as on the first day and 120 meters less than on the third day. We need to calculate the total distance they walked in these three days and express the answer in kilometers.

Solution

To find the total distance walked by the "Korotyshki" in these three days, we need to add up the distances walked on each day.

Let's break down the information given: - On the first day, they walked 940 meters. - On the second day, they walked half as much as on the first day and 120 meters less than on the third day.

Let's assign variables to the distances walked on each day: - Distance walked on the first day: d1 = 940 meters - Distance walked on the second day: d2 = half of the distance walked on the first day - 120 meters - Distance walked on the third day: d3 = unknown

To find the distance walked on the third day (d3), we can use the information that the distance walked on the second day is half of the distance walked on the first day minus 120 meters. Mathematically, this can be represented as:

d2 = (d1 / 2) - 120

We can substitute the value of d1 into this equation:

d2 = (940 / 2) - 120

Simplifying the equation:

d2 = 470 - 120

d2 = 350 meters

Now that we know the distance walked on the second day (d2), we can find the distance walked on the third day (d3). We know that the distance walked on the third day is 120 meters more than the distance walked on the second day. Mathematically, this can be represented as:

d3 = d2 + 120

Substituting the value of d2 into this equation:

d3 = 350 + 120

d3 = 470 meters

To find the total distance walked in these three days, we need to add up the distances walked on each day:

Total distance = d1 + d2 + d3

Substituting the values of d1, d2, and d3 into this equation:

Total distance = 940 + 350 + 470

Total distance = 1760 meters

To express the answer in kilometers, we need to convert meters to kilometers by dividing the total distance by 1000:

Total distance in kilometers = 1760 / 1000

Total distance in kilometers = 1.76 kilometers

Therefore, the "Korotyshki" walked a total distance of 1.76 kilometers in these three days.

Answer

The "Korotyshki" from the "Flower City" walked a total distance of 1.76 kilometers in these three days.
