Question

Сделайте действия) Скорость полета скворца 19,5м/с, а стрижа - в 1,4 раза больше. На сколько метров меньше пролетит скворец, чем стриж: 1) за 1с; 2) за 1 мин?

Answer 1

1) 19,5 * 1,4 = 27,3 м/с скорость стрижа
2) 19,5 * 1 = 19,5 метров пролетит скворец за 1 с
3) 27,3 * 1 = 27,3 метров пролетит стриж за 1 с
4) 27,3 - 19,5 = 7,8 метров, настолько меньше пролетит скворец, чем стриж за 1 сек
5) 19,5 * 60 с (1 мин = 60 сек) = 1170 метров пролетит скворец за 1 мин
6) 27,3 * 60 = 1638 метров пролетит стриж за 1 мин
7) 1638 - 1170 = 468 метров, настолько меньше пролетит скворец, чем стриж за 1 минуту

Answer 2

Calculation of the Difference in Flight Distance between a Swallow and a Swift

To calculate the difference in flight distance between a swallow and a swift, we need to compare their speeds and the time of flight.

Given: - The flight speed of a swallow is 19.5 m/s. - The flight speed of a swift is 1.4 times faster than that of a swallow.

We need to find the difference in flight distance for two scenarios: 1) For a time duration of 1 second. 2) For a time duration of 1 minute.

Calculation for 1 Second

To calculate the difference in flight distance between a swallow and a swift for a time duration of 1 second, we can use the following formula:

Flight Distance = Speed x Time

Let's calculate the flight distance for both the swallow and the swift for 1 second:

1) Swallow: - Speed: 19.5 m/s - Time: 1 second - Flight Distance of Swallow = 19.5 m/s x 1 second = 19.5 meters

2) Swift: - Speed: 1.4 times faster than the swallow's speed - Swift's Speed = 1.4 x 19.5 m/s = 27.3 m/s - Time: 1 second - Flight Distance of Swift = 27.3 m/s x 1 second = 27.3 meters

To find the difference in flight distance, we subtract the flight distance of the swallow from the flight distance of the swift:

Difference in Flight Distance = Flight Distance of Swift - Flight Distance of Swallow

Difference in Flight Distance = 27.3 meters - 19.5 meters = 7.8 meters

Therefore, the swallow will fly 7.8 meters less than the swift in 1 second.

Calculation for 1 Minute

To calculate the difference in flight distance between a swallow and a swift for a time duration of 1 minute, we need to convert the time from minutes to seconds.

1 minute = 60 seconds

Using the same formula as before, let's calculate the flight distance for both the swallow and the swift for 1 minute:

1) Swallow: - Speed: 19.5 m/s - Time: 60 seconds - Flight Distance of Swallow = 19.5 m/s x 60 seconds = 1170 meters

2) Swift: - Speed: 1.4 times faster than the swallow's speed - Swift's Speed = 1.4 x 19.5 m/s = 27.3 m/s - Time: 60 seconds - Flight Distance of Swift = 27.3 m/s x 60 seconds = 1638 meters

To find the difference in flight distance, we subtract the flight distance of the swallow from the flight distance of the swift:

Difference in Flight Distance = Flight Distance of Swift - Flight Distance of Swallow

Difference in Flight Distance = 1638 meters - 1170 meters = 468 meters

Therefore, the swallow will fly 468 meters less than the swift in 1 minute.

Conclusion

To summarize, the difference in flight distance between a swallow and a swift is as follows: 1) For a time duration of 1 second, the swallow will fly 7.8 meters less than the swift. 2) For a time duration of 1 minute, the swallow will fly 468 meters less than the swift.

Please note that these calculations are based on the given information and assumptions about the flight speeds of swallows and swifts.
