Question

Стрекоза,двигаясь со скоростью 12м/с,была в пути 5 с. С какой скоростью должна лететь бабочка, что бы преодолеть это расстояние за 15 с решение задачи

Answer 1

1) 12*5=60 м летела стрекоза
2) 60:15=4 м/с скорость бабочки

Answer 2

Сколько метров пролетела стрекоза
12*5=60м
какая скорость бабочки
60:15=4м/с
ответ:скорость бабочки 4 м/с

Answer 3

Problem Analysis

We are given that a dragonfly travels a distance in 5 seconds with a speed of 12 m/s. We need to find the speed at which a butterfly should fly in order to cover the same distance in 15 seconds.

Solution

To solve this problem, we can use the formula:

Speed = Distance / Time

Let's calculate the distance traveled by the dragonfly in 5 seconds:

Distance = Speed × Time

Substituting the given values:

Distance = 12 m/s × 5 s = 60 m

Now, we need to find the speed at which the butterfly should fly to cover the same distance in 15 seconds. Let's use the formula:

Speed = Distance / Time

Substituting the values:

Speed = 60 m / 15 s = 4 m/s

Therefore, the butterfly should fly at a speed of 4 m/s to cover the same distance in 15 seconds.

Answer

The butterfly should fly at a speed of 4 m/s to cover the same distance in 15 seconds.
