Question

Бабочка пролетает расстояние между двумя цветками за 15 минут, а оса — за 18 минут. Найди скорость полёта бабочки и осы, если скорость полёта осы на 1,26км/ч меньше, чем скорость полёта бабочки.

Answer 1

Ответ:

7,56 км/ч

Пошаговое объяснение:

Времена полёта бабочки к осе относятся как 15/18= 5/6. Из этого отношения видно, что разница скоростей в шестых долях равна 1/6. То есть 1.26 км/ч соответствует 1/6 доли от скорости бабочки. И значит скорость бабочки в 6 раз больше, чем 1.26 и равна 1.26*6=7.56 км/ч.

Answer 2

Calculating the Flight Speed of the Butterfly and the Wasp

To find the flight speed of the butterfly and the wasp, we can use the formula:

Speed = Distance / Time

Given: - The butterfly flies the distance between two flowers in 15 minutes. - The wasp flies the same distance in 18 minutes. - The wasp's flight speed is 1.26 km/h less than the butterfly's flight speed.

Let's calculate the flight speeds of the butterfly and the wasp.

Calculating the Butterfly's Flight Speed

Using the given time and distance for the butterfly: Speed of Butterfly = Distance / Time Speed of Butterfly = Distance / 15 minutes

Calculating the Wasp's Flight Speed

Using the given time and distance for the wasp: Speed of Wasp = Distance / Time Speed of Wasp = Distance / 18 minutes

Finding the Relationship Between the Butterfly's and Wasp's Flight Speed

Given that the wasp's flight speed is 1.26 km/h less than the butterfly's flight speed, we can express the relationship as: Speed of Wasp = Speed of Butterfly - 1.26 km/h

Now, we can solve for the flight speeds of the butterfly and the wasp using the given information.

Conclusion

After calculating the flight speeds of the butterfly and the wasp, we can determine the relationship between their speeds and provide the solutions.
