Question

На дахах двох будинків сиділи два голуби. Одночасно вони полетіли назустріч один одному. Один із голубів ле- тів зі швидкістю 30 м/с, а інший зі швидкістю 20 м/с. За 40 с відстань між голубами становила 125 м. Знайди відстань між будинками.​

Answer 1

Ответ:

30*40 = 1200 м(1 голубь)

20*40 = 800 м(2 голубь)

1200+800+125=2125 м(общее расстояние)

Answer 2

To find the distance between the buildings, we can use the formula:

Distance = Speed * Time

Let's calculate the time it took for the birds to meet each other. Since they flew towards each other, their relative speed would be the sum of their individual speeds:

Relative Speed = Speed of Bird 1 + Speed of Bird 2

Given that Bird 1 flew at a speed of 30 m/s and Bird 2 flew at a speed of 20 m/s, the relative speed would be:

Relative Speed = 30 m/s + 20 m/s = 50 m/s

Now, we can calculate the time it took for the birds to meet each other using the formula:

Time = Distance / Relative Speed

Given that the distance between the birds was 125 m and the relative speed was 50 m/s, the time it took for the birds to meet each other would be:

Time = 125 m / 50 m/s = 2.5 s

Since the birds flew towards each other for 40 s, we can subtract the time it took for them to meet from the total time to find the time
