Question

задача 23 аэродрома одновременно поднялись два вертолёта которые полетели в направлении на противоположных направлениях Один из вертолета в со скоростью летел со скоростью 240 километров час а другой 108 километров час на каком расстоянии друг от друга Они будут через 3 часа Реши задачу разными способами

Answer 1

1 способ.
1)240*3=720км. - пролетел 1 вертолет.
2)108*3=324км. - пролетел 2 вертолет.
3)720+324=1054км. - расстояние на котором они находятся друг от друга.
2 способ
1)240+108=358км.- их общая скорость.
2)358*3=1054км.

Answer 2

1) 240+108=348 км/ч - скорость отдаления.
    348·3=1044 км. - будет расстояние.
2) (240+108)·3=348·3=1044 км.

3) 240·3=720 км. - пролетит первый вертолёт.
    108·3=324 км. - пролетит второй вертолёт.
    720+324=1044 км. - расстояние на котором вертолёты будут через 3 часа.

Answer 3

Problem Analysis

We have two helicopters that took off simultaneously from an airport and flew in opposite directions. One helicopter flew at a speed of 240 kilometers per hour, while the other flew at a speed of 108 kilometers per hour. We need to determine the distance between the two helicopters after 3 hours.

Solution 1: Using Relative Speed

To solve this problem, we can consider the relative speed between the two helicopters. The relative speed is the difference between their individual speeds. Let's calculate the relative speed first:

Relative speed = Speed of the first helicopter - Speed of the second helicopter

Relative speed = 240 km/h - 108 km/h = 132 km/h

Now, we can calculate the distance between the two helicopters after 3 hours using the formula:

Distance = Relative speed * Time

Distance = 132 km/h * 3 hours = 396 kilometers

Therefore, the two helicopters will be 396 kilometers apart after 3 hours.

Solution 2: Using Distance = Speed * Time

Alternatively, we can calculate the distance traveled by each helicopter individually and then find the difference between their distances. Let's calculate the distance traveled by each helicopter:

Distance traveled by the first helicopter = Speed of the first helicopter * Time

Distance traveled by the first helicopter = 240 km/h * 3 hours = 720 kilometers

Distance traveled by the second helicopter = Speed of the second helicopter * Time

Distance traveled by the second helicopter = 108 km/h * 3 hours = 324 kilometers

Now, we can find the distance between the two helicopters by subtracting the distance traveled by the second helicopter from the distance traveled by the first helicopter:

Distance between the two helicopters = Distance traveled by the first helicopter - Distance traveled by the second helicopter

Distance between the two helicopters = 720 kilometers - 324 kilometers = 396 kilometers

Therefore, the two helicopters will be 396 kilometers apart after 3 hours.

Conclusion

Both methods yield the same result. The two helicopters will be 396 kilometers apart after 3 hours, regardless of the method used to calculate the distance.
