Question

Помогите пожалуйста решить задачу с условием.Две оленьих упряжки выехали одновременно навстречу друг другу и через 12 ч встретились.Одна упряжка ехала со скоростью 12км/в час а другая со скоростью 15 км/час.Сколько километров было между ними сначала?

Answer 1

Ответ:

Изначально между ними было 324 км

Пошаговое объяснение:

12*12=144 - расстояние которое проехала одна упряжка

15*1 2=180 - расстояние которая проехала вторая упряжка

180 + 144 =324 км - расстояние которое было между ними изначально

Answer 2

Problem Analysis

We are given that two reindeer teams started simultaneously and met after 12 hours. One team was traveling at a speed of 12 km/h, while the other team was traveling at a speed of 15 km/h. We need to find the distance between them at the beginning.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's assume that the distance between the two teams at the beginning is d kilometers.

The first team traveled for 12 hours at a speed of 12 km/h, so the distance it covered is 12 × 12 = 144 kilometers.

The second team also traveled for 12 hours at a speed of 15 km/h, so the distance it covered is 12 × 15 = 180 kilometers.

Since they met after 12 hours, the total distance covered by both teams is equal to the initial distance between them plus the distance covered by each team. Therefore, we can write the equation:

d + 144 + 180 = 12 × (12 + 15)

Simplifying the equation:

d + 324 = 12 × 27

d + 324 = 324

Subtracting 324 from both sides:

d = 0

Therefore, the initial distance between the two teams was 0 kilometers.

Answer

The initial distance between the two reindeer teams was 0 kilometers.
