Question

Скорсть полёта вороны равна 50 км/ ч, что составляет 5/ 9 скорости полёта утки, а скорость полета утки составляет 5/7 полёта чайки. Найдите скорость полёта чайки

Answer 1

Скорость утки=50 разделить на 5/9=90 км/час,
скорость чайки=90 разделить на 5/7=126 км/час.

Answer 2

I can understand and communicate fluently in Russian. I will try to answer your question in detail.

The user asked me to find the speed of a seagull, given that the speed of a crow is 50 km/h, which is 5/9 of the speed of a duck, and the speed of a duck is 5/7 of the speed of a seagull.

To solve this problem, I can use the following steps:

- Find the speed of a duck, by multiplying the speed of a crow by 9/5. This is because the speed of a crow is 5/9 of the speed of a duck, so the speed of a duck is 9/5 of the speed of a crow. - Find the speed of a seagull, by multiplying the speed of a duck by 7/5. This is because the speed of a duck is 5/7 of the speed of a seagull, so the speed of a seagull is 7/5 of the speed of a duck.

Using these steps, I can write the following equations:

$$ \begin{aligned} v_{\text{duck}} &= v_{\text{crow}} \cdot \frac{9}{5} \\ v_{\text{seagull}} &= v_{\text{duck}} \cdot \frac{7}{5} \end{aligned} $$

where $v_{\text{crow}}$, $v_{\text{duck}}$, and $v_{\text{seagull}}$ are the speeds of the crow, the duck, and the seagull, respectively.

Substituting the given value of $v_{\text{crow}} = 50$ km/h, I can calculate the values of $v_{\text{duck}}$ and $v_{\text{seagull}}$ as follows:

$$ \begin{aligned} v_{\text{duck}} &= 50 \cdot \frac{9}{5} \\ &= 90 \text{ km/h} \\ v_{\text{seagull}} &= 90 \cdot \frac{7}{5} \\ &= 126 \text{ km/h} \end{aligned} $$

Therefore, the speed of a seagull is 126 km/h.

This answer is consistent with one of the web search results that I found.
