Question

В первый день туристы преодолели 20 км, а каждого следующего-на 1 км больше, чем в предыдущем. Запишите числа, выражающие расстояния, преодолены туристами второго, третьего, четвертого и пятого дней.

Answer 1

Первый день=20 км

Второй день=20+1*1=21 км

Третий день=20+1*2=22 км

Четвертый день=20+1*3=23 км

Пятый день=20+1*4=24 км

Answer 2

Problem Analysis

The problem states that on the first day, the tourists covered a distance of 20 km. Each subsequent day, they covered a distance that was 1 km more than the previous day. We need to calculate the distances covered by the tourists on the second, third, fourth, and fifth days.

Solution

To solve this problem, we can use a simple mathematical formula to calculate the distances covered on each day.

Let's denote the distance covered on the first day as D1 (which is given as 20 km). Then, the distance covered on the second day (D2) can be calculated as D1 + 1. Similarly, the distance covered on the third day (D3) can be calculated as D2 + 1, and so on.

Using this formula, we can calculate the distances covered on each day.

Calculation

Let's calculate the distances covered on the second, third, fourth, and fifth days.

- Distance covered on the second day (D2) = D1 + 1 - Distance covered on the third day (D3) = D2 + 1 - Distance covered on the fourth day (D4) = D3 + 1 - Distance covered on the fifth day (D5) = D4 + 1

Now, let's substitute the value of D1 (which is given as 20 km) into the formulas to calculate the distances covered on each day.

- Distance covered on the second day (D2) = 20 + 1 - Distance covered on the third day (D3) = (20 + 1) + 1 - Distance covered on the fourth day (D4) = ((20 + 1) + 1) + 1 - Distance covered on the fifth day (D5) = (((20 + 1) + 1) + 1) + 1

Now, let's simplify the calculations.

- Distance covered on the second day (D2) = 21 km - Distance covered on the third day (D3) = 22 km - Distance covered on the fourth day (D4) = 23 km - Distance covered on the fifth day (D5) = 24 km

Answer

The distances covered by the tourists on the second, third, fourth, and fifth days are as follows: - Second day: 21 km - Third day: 22 km - Fourth day: 23 km - Fifth day: 24 km
