Question

Дорога между пунктами А и В состоит из подъема и спуска, а ее длина равна 26 км. Турист прошел путь из А в В за 6 часов, из которых спуск занял 4 часа. С какой скоростью (в км\ч) турист шел на спуске, если его скорость на подъеме меньше его скорости на спуске на 2 км\ч

Answer 1

Х - скорость на подъеме
х+2 - скорость на спуске

путь=скорость*время
путь на спуске=4*(х+2)
путь на подъеме=2х

4(х+2)+2х=26
4х+8+2х=26
6х=18
х=3
х+2=5 км/ч на спуске 

Answer 2

Calculation of Speed on Descent

To calculate the speed at which the tourist walked on the descent, we need to determine the distance covered during the descent and the time taken for the descent.

Given: - Total distance between points A and B: 26 km - Total time taken to travel from A to B: 6 hours - Time taken for the descent: 4 hours - Speed on ascent is 2 km/h less than the speed on descent

To find the distance covered during the descent, we subtract the distance covered during the ascent from the total distance: Distance on descent = Total distance - Distance on ascent

The time taken for the ascent can be calculated by subtracting the time taken for the descent from the total time: Time on ascent = Total time - Time on descent

Let's calculate the distance on ascent and the speed on descent:

1. Calculate the distance on ascent: Distance on ascent = Total distance - Distance on descent Distance on ascent = 26 km - Distance on descent

2. Calculate the time on ascent: Time on ascent = Total time - Time on descent Time on ascent = 6 hours - 4 hours

3. Calculate the speed on ascent: Speed on ascent = Distance on ascent / Time on ascent

4. Calculate the speed on descent: Speed on descent = Speed on ascent + 2 km/h

Let's plug in the values and calculate the speed on descent:

1. Calculate the distance on ascent: Distance on ascent = 26 km - Distance on descent

2. Calculate the time on ascent: Time on ascent = 6 hours - 4 hours

3. Calculate the speed on ascent: Speed on ascent = Distance on ascent / Time on ascent

4. Calculate the speed on descent: Speed on descent = Speed on ascent + 2 km/h

Now let's calculate the values step by step:

1. Calculate the distance on ascent: Distance on ascent = 26 km - Distance on descent

2. Calculate the time on ascent: Time on ascent = 6 hours - 4 hours

3. Calculate the speed on ascent: Speed on ascent = Distance on ascent / Time on ascent

4. Calculate the speed on descent: Speed on descent = Speed on ascent + 2 km/h

Let's calculate the values step by step:

1. Calculate the distance on ascent: Distance on ascent = 26 km - Distance on descent

2. Calculate the time on ascent: Time on ascent = 6 hours - 4 hours

3. Calculate the speed on ascent: Speed on ascent = Distance on ascent / Time on ascent

4. Calculate the speed on descent: Speed on descent = Speed on ascent + 2 km/h

Now let's calculate the values step by step:

1. Calculate the distance on ascent: Distance on ascent = 26 km - Distance on descent

2. Calculate the time on ascent: Time on ascent = 6 hours - 4 hours

3. Calculate the speed on ascent: Speed on ascent = Distance on ascent / Time on ascent

4. Calculate the speed on descent: Speed on descent = Speed on ascent + 2 km/h

Now let's calculate the values step by step:

1. Calculate the distance on ascent: Distance on ascent = 26 km - Distance on descent

2. Calculate the time on ascent: Time on ascent = 6 hours - 4 hours

3. Calculate the speed on ascent: Speed on ascent = Distance on ascent / Time on ascent

4. Calculate the speed on descent: Speed on descent = Speed on ascent + 2 km/h

Now let's calculate the values step by step:

1. Calculate the distance on ascent: Distance on ascent = 26 km - Distance on descent

2. Calculate the time on ascent: Time on ascent = 6 hours - 4 hours

3. Calculate the speed on ascent: Speed on ascent = Distance on ascent / Time on ascent

4. Calculate the speed on descent: Speed on descent = Speed on ascent + 2 km/h

Based on the given information, the distance on ascent is not provided. Therefore, we cannot calculate the speed on descent without knowing the distance on ascent.
