Question

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

Answer 1

2мин30сек+2мин=4мин30сек-летел воробей

650м/мин Х 4мин30сек=2925 метров-пролетел воробей

710м/мин Х 2мин30сек=1775метров-пролетела ворона

2925+1775=4700 метров-расстояние

 

 

 

 

 

 

Answer 2

1. 710 м/мин х 2. 5 мин  =  1775 м    -пролетела ворона за 2 с половиной минуты ( 2 митн.30 сек  = 2.5 мин)

 

2.  ( 2.5 мин + 2 мин) х 650  = 4.5 мин х 650 =  2925м -  пролетел воробей

 

3. 1775 + 2925 =  4 700 м -  расстояние между ними

Answer 3

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 takeoff.

Given information: - 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 convert the time to minutes. 30 seconds is equal to 0.5 minutes.

Therefore, the total time difference is 2 minutes + 0.5 minutes = 2.5 minutes.

Now, we can calculate the distance traveled by each bird using the formula:

Distance = Speed x Time

For the crow: Distance traveled by the crow = 710 m/min x 2.5 min = 1775 meters

For the sparrow: Distance traveled by the sparrow = 650 m/min x 2 min = 1300 meters

To find the distance between them, we subtract the distance traveled by the sparrow from the distance traveled by the crow:

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

Therefore, the distance between the sparrow and the crow after 2 minutes and 30 seconds will be 475 meters.
