Question

С двух аэродромов одновременно вылетели навстречу друг другу два самолета и встретились через 3 ч. Скорость первого самолета 600 км в час, а второго 900км/ч. Найдите расстояние между аэродромами.

Answer 1

3 * (600 + 900) = 3 * 1500 = 4500 

ответ 4500 км

 

 

 

 

Answer 2

Problem Analysis

We are given that two planes took off simultaneously from two different airports and met each other after 3 hours. The speed of the first plane is 600 km/h, and the speed of the second plane is 900 km/h. We need to find the distance between the two airports.

Solution

To find the distance between the two airports, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by each plane and then find the total distance between the airports.

The first plane traveled at a speed of 600 km/h for 3 hours, so the distance traveled by the first plane is:

Distance of the first plane = Speed of the first plane × Time = 600 km/h × 3 h = 1800 km.

Similarly, the second plane traveled at a speed of 900 km/h for 3 hours, so the distance traveled by the second plane is:

Distance of the second plane = Speed of the second plane × Time = 900 km/h × 3 h = 2700 km.

To find the total distance between the airports, we can add the distances traveled by each plane:

Total distance = Distance of the first plane + Distance of the second plane = 1800 km + 2700 km = 4500 km.

Therefore, the distance between the two airports is 4500 km.

Answer

The distance between the two airports is 4500 km.
