Question

Помогите решить задачу с помощью уравнений. Из двух городов, между которыми 2400 км пути, одновременно навстречу друг другу вылетели два самолета. Они встретились в аэропорту через 4 ч. Найди скорость второго самолета, если первый самолёт летел со скоростью 350 км/ч.

Answer 1

S=Vt


x-скорость второго
x+350-скорость сближения

(x+350)×4=2400
x+350=2400÷4
x+350=600
x=600-350
x=250 км /ч-скорость второго самолёта

Answer 2

2400:4=600км/ч скорость обоих самолетов
600-350=250км/ч летел второй самолет
ответ 250км/ч

Answer 3

Solving the Problem Using Equations

To solve this problem, we can use the formula:

distance = speed × time

Let's denote the speed of the first plane as v1 and the speed of the second plane as v2. The total distance between the two cities is 2400 km. When the two planes meet, they have traveled for 4 hours.

The equation for the first plane is: 2400 = 350 × 4

Now, we can use this equation to find the speed of the second plane.

Calculating the Speed of the Second Plane

Using the equation for the first plane, we can solve for the speed of the second plane:

2400 = 350 × 4 2400 = 1400

To find the speed of the second plane, we can rearrange the equation: 2400 = v2 × 4

Solving for v2: v2 = 2400 / 4 v2 = 600 km/h

So, the speed of the second plane is 600 km/h.

This calculation is based on the given information and the principles of distance, speed, and time.
