Question

Скорость полёта вороны равна 50км/ч, что составляет пять девятых скорости полёта утки, а скорость полёта утки составляет пять седьмых скорости полёта чайки. Найдите скорость полёта чайки.

Answer 1

50:5/9 = 50*9/5 = 10*9 = 90 км/ч - скорость полёта утки.
90:5/7 = 90*7/5 = 18*7 = 126 км/ч - скорость полёта чайки.

Answer 2

1)50:5*9=90(км/ч)-скорость утки
2)90:5=18(км/)-скорость чайки.
Ответ:18км/ч

Answer 3

Calculation of Seagull's Flight Speed

To find the flight speed of a seagull, we need to use the given information about the flight speeds of a crow and a duck.

According to the information provided, the flight speed of a crow is 50 km/h, which is equal to five-ninths of the flight speed of a duck. Additionally, the flight speed of a duck is equal to five-sevenths of the flight speed of a seagull.

Let's calculate the flight speed of a seagull step by step:

1. We know that the flight speed of a crow is 50 km/h. 2. The flight speed of a duck is five-ninths of the flight speed of a crow. Therefore, the flight speed of a duck can be calculated as follows:

Flight speed of a duck = (5/9) * 50 km/h

Simplifying the equation, we find:

Flight speed of a duck = 250/9 km/h

3. Finally, the flight speed of a seagull is five-sevenths of the flight speed of a duck. Therefore, the flight speed of a seagull can be calculated as follows:

Flight speed of a seagull = (5/7) * (250/9) km/h

Simplifying the equation, we find:

Flight speed of a seagull ≈ 178.57 km/h

Therefore, the flight speed of a seagull is approximately 178.57 km/h.
