Question

Воробей и ворона полетели с крыши в разных направлениях воронка со скоростью 710 метров в минуту а воробей 650 метров в минуту какое расстояние между воробьем вороны будет через две минуты 30 секунд если воробей вылетел на две минуты раньше

Answer 1

1) 2мин 30сек+2 мин=4мин 30сек такое время летел воробей.

2)2мин 30сек=2,5 мин

710*2.5=1775(м)-пролетит ворона.

3)4мин 30сек=4,5мин

650*4,5=2925(м)-пролетит воробей.

4)1775+2925=4700(м)-будет между вороной и воробьём.

4700м=4.7км

Ответ:4,7км.

Answer 2

Calculation of Distance Between Sparrow and Crow

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

Given information: - Crow's speed: 710 meters per minute - Sparrow's speed: 650 meters per minute - Time difference: The sparrow took off 2 minutes and 30 seconds later than the crow

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

Distance covered by the crow: The crow's speed is 710 meters per minute. Therefore, in 2 minutes and 30 seconds (or 2.5 minutes), the crow would cover a distance of: 710 meters/minute * 2.5 minutes = 1775 meters

Distance covered by the sparrow: The sparrow's speed is 650 meters per minute. However, the sparrow took off 2 minutes and 30 seconds later than the crow. So, the sparrow would have been flying for 2 minutes less than the crow. Therefore, the time for which the sparrow flew is: 2.5 minutes - 2 minutes = 0.5 minutes

In 0.5 minutes, the sparrow would cover a distance of: 650 meters/minute * 0.5 minutes = 325 meters

Now, to find the distance between the sparrow and the crow, we subtract the distance covered by the sparrow from the distance covered by the crow:

1775 meters - 325 meters = 1450 meters

Therefore, the distance between the sparrow and the crow after 2 minutes and 30 seconds would be 1450 meters.

Please note that the above calculation assumes that the birds are flying in a straight line and at a constant speed.
