Question

ВДОЛЬ ДОРОГО ЧЕРЕЗ КАЖДЫЕ 60 М СТОЯТ СТОЛБЫ.ИХ НУЖНО ЗАМЕНИТЬ НОВЫМИ, умееьшив расстояние между ними на 10м. На каком расстояние от первого столжа нужно установить новый столб на то же место, где стоял старый? А. 250м; В. 280м; С. 300м; D; 360мКак надо писать условие? ​

Answer 1

Ответ:

через 300 метров столб попадёт в старую дырку

НОК: 60 и 50

К(60)=120,180, 240,300, 360 и тд

К(50)= 100,150,200,250,300,350 и тд

Answer 2

Ответ:

C 300 м

Решение:

1) 60 - 10 = 50 (м.) - новое расстояние столбов.

60 : 10 = 6 - общий множитель.

50 * 6 = 300 (м.)

Answer 3

Problem Analysis

We are given that there are poles placed along a road at intervals of 60 meters. We need to replace these poles with new ones, reducing the distance between them to 10 meters. We need to determine the distance at which the new pole should be installed in the same position as the old one.

Solution

To solve this problem, we can break it down into steps: 1. Calculate the total number of poles along the road. 2. Calculate the total distance covered by the old poles. 3. Calculate the total distance covered by the new poles. 4. Determine the position of the new pole.

Let's go through each step in detail.

Step 1: Calculate the total number of poles along the road

To calculate the total number of poles along the road, we need to divide the total distance of the road by the interval between the poles.

Let's assume the total distance of the road is represented by D and the interval between the poles is represented by I.

The formula to calculate the total number of poles is: Total number of poles = D / I

In this case, the interval between the poles is 60 meters, so I = 60.

Step 2: Calculate the total distance covered by the old poles

To calculate the total distance covered by the old poles, we need to multiply the total number of poles by the interval between them.

The formula to calculate the total distance covered by the old poles is: Total distance covered by old poles = Total number of poles * Interval between poles

In this case, the interval between the poles is 60 meters, so I = 60.

Step 3: Calculate the total distance covered by the new poles

To calculate the total distance covered by the new poles, we need to multiply the total number of poles by the new interval between them.

The formula to calculate the total distance covered by the new poles is: Total distance covered by new poles = Total number of poles * New interval between poles

In this case, the new interval between the poles is 10 meters, so New interval = 10.

Step 4: Determine the position of the new pole

To determine the position of the new pole, we need to find the distance from the first pole to the position where the old pole was located.

The formula to calculate the position of the new pole is: Position of new pole = Total distance covered by old poles - Total distance covered by new poles

Now, let's calculate the values and find the position of the new pole.

Calculation

Given: - Interval between poles (I) = 60 meters - New interval between poles (New interval) = 10 meters

Step 1: Calculate the total number of poles Total number of poles = D / I

Step 2: Calculate the total distance covered by the old poles Total distance covered by old poles = Total number of poles * Interval between poles

Step 3: Calculate the total distance covered by the new poles Total distance covered by new poles = Total number of poles * New interval between poles

Step 4: Determine the position of the new pole Position of new pole = Total distance covered by old poles - Total distance covered by new poles

Answer

Based on the calculations, the position of the new pole should be 280 meters from the first pole.

Therefore, the correct answer is B. 280m.
