Question

Туристы прошли намеченный маршрут за три дня. В первый день они прошли 35% намеченного маршрута, во 2 день на 3 км больше ,чем в первый, а в 3 -оставшиеся 21 км.Какова длина маршрута?

Answer 1

х - длина маршрута

35% = 0,35

0,35х - прошли в первый день

0,35х+3 - прошли во второй день

х=0,35х+0,35х+3+21

0,3х=24

х=80 (км) - длина маршрута

.............................................................................................................................................

Answer 2

пусть длина маршрута х км. тогда в 1 они прошли 0,35х км, во 2 0,35х +3, а в 3 день 21 км. всего маршрут составлял 0,35х+0,35х+3+21 или х

0,35х+0,35х+3+21= х

 х-0,7х=24

0,3х=24

     х=80

значит маршрут равен 80 км.

 

Answer 3

Calculation of the Length of the Route

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

1. On the first day, the tourists walked 35% of the planned route. 2. On the second day, they walked 3 km more than on the first day. 3. On the third day, they walked the remaining 21 km of the route.

To find the total length of the route, we need to determine the distance covered on each day and add them together.

Calculation Steps:

1. Calculate the distance covered on the first day: - Let's assume the total length of the route is represented by "x" km. - The tourists walked 35% of the route on the first day, which is 0.35x km.

2. Calculate the distance covered on the second day: - On the second day, they walked 3 km more than on the first day. - So, the distance covered on the second day is 0.35x + 3 km.

3. Calculate the distance covered on the third day: - On the third day, they walked the remaining 21 km of the route.

4. Add up the distances covered on each day to find the total length of the route: - (0.35x) + (0.35x + 3) + 21 = x

Now, let's solve the equation to find the value of "x" and determine the length of the route.

Solving the Equation:

(0.35x) + (0.35x + 3) + 21 = x

0.35x + 0.35x + 3 + 21 = x

0.7x + 24 = x

24 = x - 0.7x

24 = 0.3x

x = 24 / 0.3

x = 80

Therefore, the length of the route is 80 km.
