Question

В безветренный день бабочка летает в своём домике со скоростью 18 км/ч. С какой скоростью бабочка полетит по направлению ветра, если его скорость будет 2 км/ч? Какова будет её скорость, если она полетит против ветра? Скорость бабочки по направлению ветра равна ........ км/ч Скорость бабочки против ветра равна..........км/ч. ПЖ ПОМОГИТЕ (заранее спасибо вы лучшие)

Answer 1

Ответ:

скорость по направлению равна 18+2=20 км/ч

Скорость против ветра равна 18-2=16 км/ч

Answer 2

Ответ:

Пошаговое объяснение:

Скорость бабочки 18 км/час

Скорость ветра 3км/час

18+3=21км/час скорость по ветру

18-3=15км/час скорость против ветра

Answer 3

Calculation of Butterfly's Speed with the Wind

To calculate the speed of the butterfly flying with the wind, we need to consider the relative motion between the butterfly and the wind. In this case, the butterfly is flying in a windless environment with a speed of 18 km/h, and the wind starts blowing in the same direction as the butterfly's flight with a speed of 2 km/h.

To find the speed of the butterfly with the wind, we can add the speed of the wind to the butterfly's original speed. Therefore, the speed of the butterfly with the wind will be:

Speed of the butterfly with the wind = Butterfly's speed + Wind speed

Substituting the given values:

Speed of the butterfly with the wind = 18 km/h + 2 km/h = 20 km/h

Therefore, the speed of the butterfly flying with the wind will be 20 km/h.

Calculation of Butterfly's Speed against the Wind

To calculate the speed of the butterfly flying against the wind, we need to consider the relative motion between the butterfly and the wind. In this case, the butterfly is flying in a windless environment with a speed of 18 km/h, and the wind starts blowing in the opposite direction of the butterfly's flight with a speed of 2 km/h.

To find the speed of the butterfly against the wind, we can subtract the speed of the wind from the butterfly's original speed. Therefore, the speed of the butterfly against the wind will be:

Speed of the butterfly against the wind = Butterfly's speed - Wind speed

Substituting the given values:

Speed of the butterfly against the wind = 18 km/h - 2 km/h = 16 km/h

Therefore, the speed of the butterfly flying against the wind will be 16 km/h.
