Question

Из одного гнезда одновременно вылетели в противоположных направлениях две вороны через ноль целых 15 часов расстояние между ними было 7 и 8 километров скорость полета одной вороны 32 и 8 километров час Чему равна скорость полета 2 вороны

Answer 1

V=S:t
7,8 км : 0,15 час = 52 км/час (скорость удаления друг от друга или сумма скоростей)
52 км/час - 32,8 км/час = 19,2 км/час (скорость полета 2-й вороны)
Ответ: скорость полета второй вороны - 19,2 км/час

Answer 2

Calculation of the Speed of the Two Crows

To calculate the speed of the two crows, we need to determine the time it took for them to cover the given distance.

Given information: - Two crows flew in opposite directions from the same nest. - The distance between them was 7 kilometers and 8 kilometers. - The time it took for them to meet again was 15 hours. - The speed of one crow was 32 kilometers per hour, and the speed of the other crow was 8 kilometers per hour.

To find the speed of the second crow, we can set up the following equation:

Distance = Speed × Time

For the first crow: 7 km = 32 km/h × Time

For the second crow: 8 km = Speed × Time

Since we know the time is the same for both crows (15 hours), we can solve for the speed of the second crow.

Let's calculate the speed of the second crow using the given information:

For the first crow: 7 km = 32 km/h × 15 hours Simplifying the equation, we get: 7 km = 480 km Dividing both sides by 15, we find: 32 km/h = 7/15 km/h

For the second crow: 8 km = Speed × 15 hours Dividing both sides by 15, we find: Speed = 8/15 km/h

Therefore, the speed of the second crow is 8/15 km/h.

Please note that the given information does not specify which crow had the speed of 32 km/h and which had the speed of 8 km/h. The calculation above assumes that the first crow had a speed of 32 km/h and the second crow had a speed of 8 km/h.
