Question

Двое судей начали одновременно движение навстречу друг другу от двух пунктов и встретились через 20 минут.Сколько метров между пунктами,из которых вышли судьи,если первый судья делает 12 шагов в минуту,а второй 10 шагов в минуту?Длина шага у обоих судей в среднем равна 80 см.

Answer 1

1) 12+10=22 шага/мин скорость сближения 
2)  22*80=1760 см/мин скорость сближения в см
3) 1760*20=35200 см или 352 м расстояние между пунктами

Ответ 352 м расстояние между пунктами
 Думаю,что так)Помогла как смогла.

Answer 2

Problem Analysis

To solve this problem, we need to find the distance between the two points from which the judges started, given that they walked towards each other and met after 20 minutes. We also have the information about the number of steps each judge takes per minute and the average length of their steps.

Solution

Let's calculate the distance between the two points using the given information.

1. Calculate the Total Distance Covered by Each Judge: - Judge 1: 12 steps/minute * 20 minutes = Total steps taken by Judge 1 - Judge 2: 10 steps/minute * 20 minutes = Total steps taken by Judge 2

2. Calculate the Total Distance Covered by Each Judge: - Judge 1: Total steps * Length of each step - Judge 2: Total steps * Length of each step

3. Calculate the Total Distance Covered by Both Judges: - Total distance = Distance covered by Judge 1 + Distance covered by Judge 2

4. Calculate the Distance Between the Two Points: - Distance between the two points = Total distance covered by both judges

Let's perform the calculations.

Calculation

1. Calculate the Total Distance Covered by Each Judge: - Judge 1: 12 steps/minute * 20 minutes = 240 steps - Judge 2: 10 steps/minute * 20 minutes = 200 steps

2. Calculate the Total Distance Covered by Each Judge: - Judge 1: 240 steps * 80 cm = 19200 cm - Judge 2: 200 steps * 80 cm = 16000 cm

3. Calculate the Total Distance Covered by Both Judges: - Total distance = 19200 cm + 16000 cm = 35200 cm

4. Calculate the Distance Between the Two Points: - Distance between the two points = 35200 cm = 352 meters

Answer

The distance between the two points, from which the judges started, is 352 meters.
