Question

Стриж летел 14секунд со скоростью 80м/с. За сколько секунд пролетит скворец половину этого пути, если будет лететь со скоростью 20м/с?

Answer 1

1)14×80=1120(м)
2)1120÷20=56 (с)

Answer 2

1) 80*14=1120м- стриж
2) (1120:2):20=28 секунд- t скворца

Answer 3

Calculation of the Time Taken by the Swiftlet

To calculate the time taken by the swiftlet to fly half the distance at a speed of 20 m/s, we can use the formula:

Time = Distance / Speed

Given that the swiftlet flew for 14 seconds at a speed of 80 m/s, we can calculate the total distance covered:

Distance = Speed x Time

Distance = 80 m/s x 14 s = 1120 meters.

To find the time taken to fly half the distance, we divide the total distance by 2:

Half Distance = 1120 meters / 2 = 560 meters

Now, we can calculate the time taken to fly half the distance at a speed of 20 m/s:

Time = Half Distance / Speed

Time = 560 meters / 20 m/s = 28 seconds

Therefore, the swiftlet will take 28 seconds to fly half the distance at a speed of 20 m/s.

Please note that the above calculations are based on the given information and assumptions.
