Question

Две группы туристов вышли одновременно навстречу друг другу из двух сёл.расстояние между сёлами 44 км. одна группа шла со скоротью 80 км/ч.с какой скоростью шла вторая группа, если они встретились через 4 ч?

Answer 1

44:4=11 км/ч-скорость второй группы

Answer 2

Problem Analysis

We have two groups of tourists who start walking towards each other from two different villages. The distance between the villages is 44 km. One group is walking at a speed of 80 km/h. We need to find the speed at which the second group is walking, given that they meet after 4 hours.

Solution

To find the speed of the second group, we can use the formula: speed = distance / time.

Let's calculate the distance covered by the first group in 4 hours. Since they are walking at a speed of 80 km/h, the distance covered by them would be: distance = speed × time = 80 km/h × 4 h = 320 km.

Since the two groups meet after 4 hours, the total distance covered by both groups would be equal to the distance between the villages, which is 44 km. Therefore, the distance covered by the second group would be: distance = total distance - distance covered by the first group = 44 km - 320 km = -276 km.

However, a negative distance doesn't make sense in this context. It means that the second group didn't cover any distance or didn't start walking at all. This could be due to an error in the problem statement or some other factor.

Therefore, based on the given information, we cannot determine the speed at which the second group was walking.

Conclusion

Based on the given information, we cannot determine the speed at which the second group was walking. The problem statement may have some inconsistencies or missing information.
