Question

Решите пожалуйста задачу С одного улья одновременно вылетели в противоположные стороны две пчелы. Через 0.15 ч. между ними было 6.3 км. Одна пчела летела со скоростью 21.6 км/ч. Найдите скорость полета другой пчелы.

Answer 1

1) 21,6 * 0,15= 3,24км - пролетела первая пчела 
2) 6,3 - 3,24 = 3,06 км - пролетела вторая пчела 
3) 3,06 : 0,15 = 20,4 км/ч - скорость второй пчелы

Answer 2

Problem Analysis

To solve this problem, we can use the formula:

\[ \text{speed} = \frac{\text{distance}}{\text{time}} \]

We know the distance between the bees and the time it took for them to cover that distance. Using this information, we can calculate the speed of the second bee.

Calculation

The speed of the first bee is given as 21.6 km/h. The time it took for the bees to cover the distance of 6.3 km is 0.15 hours.

Using the formula, we can calculate the speed of the second bee:

\[ \text{speed} = \frac{\text{distance}}{\text{time}} = \frac{6.3 \text{ km}}{0.15 \text{ hours}} = 42 \text{ km/h} \]

The speed of the second bee is 42 km/h.
