Question

За три дні туристи пройшли 48 км. За 2 день вони пройшли 60% відстані, пройденої за перший день а за 3день 4/5відстані за перший день. Скільки км проходили туристи за кожний день

Answer 1

1-й день - х км

2-й день - 60% = 60/100 = 6/10 = 0,6х км

3-й день - 4/5 = 8/10 = 0,8х км

Всего 48 км

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Уравнение:

х + 0,6х + 0,8х = 48

2,4х = 48

х = 48 : 2,4

х = 20 (км) - пройдено в первый день

0,6х = 0,6 · 20 = 12 (км) - пройдено во второй день

0,8х = 0,8 · 20 = 16 (км) - пройдено в третий день

Ответ: 20 км, 12 км и 16 км.

Answer 2

Calculating the Distance Covered Each Day by Tourists

To calculate the distance covered by the tourists each day, we can use the information provided.

Let's denote the total distance covered by the tourists as D and the distance covered on the first day as D1.

From the given information: - The tourists covered a total distance of 48 km in three days. - On the second day, they covered 60% of the distance covered on the first day. - On the third day, they covered 4/5 of the distance covered on the first day.

Using this information, we can calculate the distance covered on each day.

Calculation

Let's start by calculating the distance covered on the first day (D1).

Given: - Total distance covered in three days = 48 km

We can set up the equation: D1 + D2 + D3 = 48

Now, we know that: - D2 = 60% of D1 - D3 = 4/5 of D1

Substituting these values into the equation: D1 + 0.6D1 + 0.8D1 = 48 2.4D1 = 48 D1 = 48 / 2.4 D1 = 20

So, the distance covered on the first day (D1) is 20 km.

Now, we can calculate the distance covered on the second day (D2) and the third day (D3).

Calculating D2 and D3

- D2 = 60% of D1 = 0.6 * 20 = 12 km - D3 = 4/5 of D1 = 0.8 * 20 = 16 km

Therefore, the distance covered by the tourists on each day is as follows: - First day: 20 km - Second day: 12 km - Third day: 16 km
