Question

С одного аэропорта вылетел самолёт, а навстречу ему с той же скоростью, через 1 час, с другого аэропорта вылетел другой самолёт и встретил первый самолёт через 3 часа. Расстояние между аэропортами 2240 км. Какова скорость самолётов? помогите прошу васпомогитеееееееееееееее

Answer 1

Problem Analysis

We are given the following information: - A plane takes off from one airport and flies towards another airport at a certain speed. - After 1 hour, another plane takes off from the second airport and meets the first plane after 3 hours. - The distance between the airports is 2240 km.

We need to find the speed of the planes.

Solution

Let's assume the speed of the first plane is x km/h and the speed of the second plane is also x km/h.

We can calculate the distance traveled by the first plane in 1 hour using the formula:

Distance = Speed × Time

For the first plane, the distance traveled in 1 hour is x km/h × 1 h = x km.

After 3 hours, the first plane has traveled a total distance of x km + 3x km = 4x km.

Since the total distance between the airports is 2240 km, we can set up the equation:

4x km = 2240 km

Solving for x, we find:

x = 2240 km / 4 = 560 km/h

Therefore, the speed of both planes is 560 km/h.

Answer

The speed of the planes is 560 km/h.
