Question

440." Із двох хуторів, відстань між якими дорів- нює 3 км, вийшли одночасно назустріч одна одній дві хуторянки. Одна з них рухалася зі швидкістю 5 км/год, а друга - зі швидкістю 4 км/год. Якою буде відстань між хуторянками через 2 год після початку руху?

Problem Analysis

We are given that two villagers start walking towards each other from two different hamlets, which are 3 km apart. One villager walks at a speed of 5 km/h, while the other walks at a speed of 4 km/h. We need to find the distance between them after 2 hours.

Solution

To find the distance between the two villagers after 2 hours, we need to calculate the total distance covered by both villagers and subtract it from the initial distance between the hamlets.

Let's calculate the distance covered by each villager after 2 hours:

- The first villager walks at a speed of 5 km/h for 2 hours, covering a distance of 5 km/h * 2 h = 10 km. - The second villager walks at a speed of 4 km/h for 2 hours, covering a distance of 4 km/h * 2 h = 8 km.

Now, let's calculate the remaining distance between the two villagers:

- The initial distance between the hamlets is 3 km. - The first villager has covered 10 km, so the remaining distance for the second villager is 3 km - 10 km = -7 km.

Since the remaining distance is negative, it means that the second villager has already passed the first villager. Therefore, the distance between the two villagers after 2 hours is the sum of the distances covered by both villagers, which is 10 km + 8 km = 18 km.

Answer

The distance between the two villagers after 2 hours will be 18 km.

Note: The negative value for the remaining distance indicates that the second villager has already passed the first villager.
