Question

Из 2 посёлков расстояние между которыми 75 километров вышли Одновременно навстречу друг другу Два лыжника 1 идет со скоростью 12 километров час а вторую со скоростью 13 километров в час Они идут уже 2 часа какое расстояние надо еще пройти до встречи Сколько времени Это займет

Answer 1

12+13=25
25*2=50
75-50=25 25/25=1 час

Answer 2

1)12+13=25(км/ч)- скорость сближения.
2)25×2=50(км)-они прошли.
3)75-50=25(км)- имнадо еще пройти.
4)25:25=1(ч)- понадобится, чтобы встретится.

Answer 3

Problem Analysis

We have two skiers who start simultaneously from two villages that are 75 kilometers apart. The first skier is moving at a speed of 12 kilometers per hour, while the second skier is moving at a speed of 13 kilometers per hour. They have been skiing for 2 hours, and we need to calculate the remaining distance they need to cover before they meet, as well as the time it will take for them to meet.

Solution

To find the remaining distance they need to cover before they meet, we can subtract the distance covered by both skiers from the total distance between the villages.

Let's calculate the distance covered by each skier: - The first skier has been skiing for 2 hours at a speed of 12 kilometers per hour. Therefore, the distance covered by the first skier is 2 hours * 12 kilometers per hour = 24 kilometers. - The second skier has also been skiing for 2 hours at a speed of 13 kilometers per hour. Therefore, the distance covered by the second skier is 2 hours * 13 kilometers per hour = 26 kilometers.

Now, let's calculate the remaining distance they need to cover before they meet: - The total distance between the villages is 75 kilometers. - The distance covered by the first skier is 24 kilometers. - The distance covered by the second skier is 26 kilometers.

To find the remaining distance, we subtract the sum of the distances covered by both skiers from the total distance between the villages: Remaining distance = Total distance - (Distance covered by the first skier + Distance covered by the second skier) Remaining distance = 75 kilometers - (24 kilometers + 26 kilometers) Remaining distance = 75 kilometers - 50 kilometers Remaining distance = 25 kilometers.

Therefore, the remaining distance they need to cover before they meet is 25 kilometers.

To calculate the time it will take for them to meet, we can use the formula: Time = Distance / Speed.

Let's calculate the time it will take for them to meet: - The remaining distance they need to cover before they meet is 25 kilometers. - The combined speed of both skiers is 12 kilometers per hour + 13 kilometers per hour = 25 kilometers per hour.

Using the formula Time = Distance / Speed, we can calculate the time it will take for them to meet: Time = Remaining distance / Combined speed Time = 25 kilometers / 25 kilometers per hour Time = 1 hour.

Therefore, it will take them 1 hour to meet.

Conclusion

The remaining distance they need to cover before they meet is 25 kilometers, and it will take them 1 hour to meet.
