Question

За 3 дня туристы прошли 38 км. За 2ой день они прошли в 2 раза больше, чем за 1ый и за третий - на 6 км больше, чем за первый. Сколько км прошли туристы за 1ый день

Answer 1

Пусть x км будет сколько туристы прошли за первый день 
x+2x+x+6=38
4x+6=38
4x=38-6
4x=32
x=32/4
x=8

Ответ:1 день-8 км

Answer 2

Calculating the Distance Covered by Tourists Each Day

To calculate the distance covered by the tourists on each day, we can use the information provided in the question. Let's break down the given information:

1. The tourists covered a total distance of 38 km over 3 days. 2. On the 2nd day, they covered twice as much distance as on the 1st day, and on the 3rd day, they covered 6 km more than on the 1st day.

Let's denote the distance covered on the 1st, 2nd, and 3rd days as D1, D2, and D3 respectively.

We can form the following equations based on the given information: - D1 + D2 + D3 = 38 (total distance covered over 3 days) - D2 = 2 * D1 (distance covered on the 2nd day is twice as much as on the 1st day) - D3 = D1 + 6 (distance covered on the 3rd day is 6 km more than on the 1st day)

Let's solve these equations to find the distance covered on the 1st day.

Solving for the Distance Covered on the 1st Day

Using the equations above, we can solve for the distance covered on the 1st day.

1. Substitute the value of D2 from the second equation into the first equation: D1 + 2 * D1 + D1 + 6 = 38 4 * D1 + 6 = 38 4 * D1 = 38 - 6 4 * D1 = 32 D1 = 32 / 4 D1 = 8 km

Therefore, the tourists covered 8 km on the 1st day.

Conclusion

The tourists covered 8 km on the 1st day.
