Question

Скорость ветра 1,78 м/с. Ласточка летит по направлению ветра со скоростью 7,4 км/с. Сколько метров пролетит ласточка за 3с против ветра?

Answer 1

7,4-1,78=5,62 м/с- скорость ласточки

(5,62-1,78)х3=3,84х3=11,52 метра пролетит ласточка против ветра

Answer 2

1) 7,4-1,78=5,62(м/с) скорость ласточки

2) 5,62-1,78=3,84 (м/с) скорость ласточки, летящей против ветра

3) 3,84*3=11,52 (м) пролетил ласточка против ветра за 3 с

Ответ: 11,52 м 

Answer 3

Calculation of Distance Traveled by the Swallow

To calculate the distance traveled by the swallow against the wind, we need to consider the relative velocities of the wind and the bird.

Given: - Wind speed: 1.78 m/s - Swallow's speed: 7.4 km/s

To calculate the distance traveled by the swallow, we can use the formula:

Distance = Speed x Time

Let's convert the swallow's speed from km/s to m/s:

Swallow's speed = 7.4 km/s = 7.4 * 1000 m/s = 7400 m/s

Now, let's calculate the distance traveled by the swallow against the wind in 3 seconds:

Time = 3 seconds

Distance = Swallow's speed x Time

Distance = 7400 m/s x 3 s = 22200 meters

Therefore, the swallow will travel 22,200 meters against the wind in 3 seconds.
