Question

Воробей и ворона полетели с крыши в разных направлениях.Ворона летела со скоростью 710м/мин,а воробей-650м/мин.Какое расстояние между воробьём и вороной будет через 2 мин 30с,если воробей вылетел на 2 мин раньше?

Answer 1

Если условие задачи предполагает, что воробей летел 2 мин 30 сек, а ворона 2 мин 30 сек - 2 мин =30 сек = 0,5 мин, то
S=Vt
710 м/мин * 0,5 мин = 355 м (пролетела ворона)
650 м/мин * 2,5 мин = 1625 м (пролетел воробей)
1625 м + 355 м = 1980 м
Ответ: между вороной и воробьем через 2 мин 30 сек будет 1980 м

Answer 2

Calculation of the Distance between the Sparrow and the Crow

To calculate the distance between the sparrow and the crow after a given time, we need to consider their speeds and the time difference between their departures.

Given: - Crow's speed: 710 m/min - Sparrow's speed: 650 m/min - Time difference: 2 minutes

To find the distance between them after 2 minutes and 30 seconds, we need to calculate the distance covered by each bird during that time.

First, let's calculate the distance covered by the crow in 2 minutes and 30 seconds: - Crow's speed: 710 m/min - Time: 2 minutes and 30 seconds = 2.5 minutes

Distance covered by the crow = Crow's speed * Time = 710 m/min * 2.5 min = 1775 meters

Next, let's calculate the distance covered by the sparrow in 2 minutes: - Sparrow's speed: 650 m/min - Time: 2 minutes

Distance covered by the sparrow = Sparrow's speed * Time = 650 m/min * 2 min = 1300 meters

Since the sparrow took off 2 minutes earlier, the distance between the sparrow and the crow after 2 minutes and 30 seconds would be the difference between the distances covered by each bird.

Distance between the sparrow and the crow = Distance covered by the crow - Distance covered by the sparrow = 1775 meters - 1300 meters = 475 meters

Therefore, the distance between the sparrow and the crow after 2 minutes and 30 seconds, with the sparrow taking off 2 minutes earlier, would be 475 meters.
