Question

Из двух древней навстречу друг другу вышли 2 пешехода. Скорость первого пешехода составляет 6,7 км/ч, а скорость втрого пешехода-4,6 км/ч. Через 2 часа и 30 минут они встретились. Каково расстояние между деревнями?

Answer 1

28 км 250 м 6.7 + 4.6 = 11.3 км 11.3 * 2.50 = 28.25 км или 28 км 250 м

Answer 2

Problem Analysis

We have two pedestrians walking towards each other. The speed of the first pedestrian is 6.7 km/h, and the speed of the second pedestrian is 4.6 km/h. After 2 hours and 30 minutes, they meet. We need to find the distance between the two villages.

Solution

To find the distance between the two villages, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by each pedestrian and then find the total distance between the villages.

1. Calculate the distance traveled by the first pedestrian: - Speed of the first pedestrian = 6.7 km/h - Time = 2 hours and 30 minutes = 2.5 hours - Distance = Speed × Time = 6.7 km/h × 2.5 hours = 16.75 km

2. Calculate the distance traveled by the second pedestrian: - Speed of the second pedestrian = 4.6 km/h - Time = 2 hours and 30 minutes = 2.5 hours - Distance = Speed × Time = 4.6 km/h × 2.5 hours = 11.5 km

3. Calculate the total distance between the villages: - Total distance = Distance traveled by the first pedestrian + Distance traveled by the second pedestrian - Total distance = 16.75 km + 11.5 km = 28.25 km

Therefore, the distance between the two villages is 28.25 km.

Answer

The distance between the two villages is 28.25 km.
