Question

Из одного гнезда одновременно в противоположных направлениях вылетели две вороны.Через 0,12 часа расстояние между ними было 7,8 км .Скорость одной вороны 32,8 км /ч.Найди скорость второй вороны

Answer 1

1)чему равна общая их скорость полета?
7,8:0,12=65 км/ч
2) чему равна скорость первой вороны?
65-32,8=32,2 км/ч
Ответ: скорость второй вороны 32,2 км/ч,

Answer 2

Given Information

Two crows flew out of the same nest in opposite directions simultaneously. After 0.12 hours, the distance between them was 7.8 km. The speed of one crow is 32.8 km/h.

Calculating the Speed of the Second Crow

To find the speed of the second crow, we can use the formula: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

Given: - Distance = 7.8 km - Time = 0.12 hours - Speed of the first crow = 32.8 km/h

Using the formula, we can calculate the speed of the second crow: \[ \text{Speed of the second crow} = \frac{7.8 \, \text{km}}{0.12 \, \text{hours}} \]

\[ \text{Speed of the second crow} = 65 \, \text{km/h} \]

So, the speed of the second crow is 65 km/h.

Verification

The speed of the second crow was calculated using the given distance and time. This calculation is consistent with the provided information.
