Question

Ворона за 3 секунды пролетает 45м.Какое растояние пролитит ворона с токой же скоростью за 8 секунд?

Answer 1

1) 45м : 3с = 15м/с - скорость вороны

2) 15м/с · 8с = 120м - пролетит ворона за 8 секунд

Answer 2

45:3=15
15×8=120
120км

Answer 3

To find out the distance the crow (ворона) will travel in 8 seconds with the same speed, we can use the concept of proportionality. The speed of the crow remains constant, so the distance it travels is directly proportional to the time it takes.

Let's set up a proportion:

Distance_1 / Time_1 = Distance_2 / Time_2

Where: Distance_1 = 45 meters (distance in the first scenario, 3 seconds) Time_1 = 3 seconds (time in the first scenario) Distance_2 = Unknown (distance in the second scenario, 8 seconds) Time_2 = 8 seconds (time in the second scenario)

Now, plug in the values and solve for Distance_2:

45 / 3 = Distance_2 / 8

To find Distance_2, cross-multiply and then divide:

Distance_2 = (45 * 8) / 3 Distance_2 = 360 / 3 Distance_2 = 120 meters

Therefore, the crow will travel 120 meters with the same speed in 8 seconds.
