Question

Туристы прошли намеченный маршрут за три дня.В первый день они прошли 30% намеченного маршрута , во второй день - на 4 км больше , чем первый ,а в третий оставшиеся 28 км.Какова длинна маршрута?

Answer 1

Весь маршрут Х ( км )
1 день 0,3х ( км )
2 день ( 0,3х + 4 ) км
3 день 28 км
Уравнение
Х = 0,3х + ( 0,3х + 4 ) + 28
Х - 0,6х = 24
0,4х = 24
Х = 60 ( км )
Ответ 60 км

Answer 2

Calculation of the Length of the Route

To calculate the length of the route, we need to analyze the information provided. Let's break it down step by step:

1. On the first day, the tourists walked 30% of the planned route. 2. On the second day, they walked 4 km more than on the first day. 3. On the third day, they walked the remaining 28 km.

Let's assume the length of the planned route is represented by the variable x.

On the first day, they walked 30% of the planned route, which is equal to 0.3x.

On the second day, they walked 4 km more than on the first day, so the distance covered on the second day is 0.3x + 4 km.

On the third day, they walked the remaining 28 km, so the distance covered on the third day is 28 km.

To find the total length of the route, we need to add up the distances covered on each day:

0.3x + (0.3x + 4) + 28 = x

Simplifying the equation:

0.3x + 0.3x + 4 + 28 = x

0.6x + 32 = x

Subtracting 0.6x from both sides:

32 = 0.4x

Dividing both sides by 0.4:

x = 80

Therefore, the length of the route is 80 km.
