Answer 1

1) 12+15=27(км\ч) скорость сближения.
2) 27*12=324(км)
Ответ: 324 км было между ними сначала

Answer 2

Problem Analysis

We are given that two reindeer teams started simultaneously towards each other. 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 determine the distance between them initially.

Solution

Let's assume that the distance between the two teams initially is x kilometers.

After 12 hours, the first team has traveled a distance of 12 km/h * 12 h = 144 km.

The second team has also traveled a distance of 15 km/h * 12 h = 180 km.

At this point, the total distance covered by both teams is 144 km + 180 km = 324 km.

Since they were traveling towards each other, the total distance covered by both teams should be equal to the initial distance between them.

Therefore, we can set up the following equation:

x = 324 km

So, the initial distance between the two teams was 324 kilometers.

Answer

The initial distance between the two reindeer teams was 324 kilometers.
