Question

Два самолёта летели с одинаковой средней скорастью, Один самолёт был в воздухе 3 ч , другой-5 ч ипролетел на 1600 км больше, чем первый. Поставь вопрос и реши задачу

Answer 1

Какова средняя скорость самолетов?

5-3=2ч разница продолжительности полета,

1600/2=800км/ч средняя скорость самолётов

Answer 2

Какова скорость самолётов?

 

Решение:

1 способ.

Пусть х-скорость самолётов, тогда первый пролетел 3х км, а второй 5х км.

По условию задачи второй самолёт пролетел на 1600 км больше чем первый.

Составляем уравнение:

5х-3х=1600

2х=1600

х=1600:2

х=800(км/ч)-скорость самолётов

 

2 способ.

1)5-3=2(ч)-на столько больше пролетел второй самолёт, чем первый

2)1600:2=800(км/ч)-скорость самолётов

Answer 3

Problem Analysis

To solve this problem, we need to find the speed of the airplanes and the distance they traveled. We are given that two airplanes flew at the same average speed. One airplane was in the air for 3 hours, while the other was in the air for 5 hours and traveled 1600 km more than the first airplane. We need to determine the speed of the airplanes and the distance each one traveled.

Problem Solution

Let's assume the speed of both airplanes is x km/h.

The first airplane was in the air for 3 hours, so the distance it traveled can be calculated as: Distance1 = Speed1 * Time1 = x * 3 km

The second airplane was in the air for 5 hours and traveled 1600 km more than the first airplane. Therefore, the distance it traveled can be calculated as: Distance2 = Speed2 * Time2 = x * 5 km

We are given that the second airplane traveled 1600 km more than the first airplane, so we can write the equation: Distance2 = Distance1 + 1600 km

Substituting the values of Distance1 and Distance2, we get: x * 5 km = x * 3 km + 1600 km

Now, let's solve this equation to find the value of x.

Solving the Equation

To solve the equation, we can simplify it by canceling out the units (km) and rearranging the terms:

5x = 3x + 1600

Subtracting 3x from both sides of the equation:

5x - 3x = 1600

Simplifying:

2x = 1600

Dividing both sides of the equation by 2:

x = 800

Therefore, the speed of both airplanes is 800 km/h.

Answer

To summarize, both airplanes flew at a speed of 800 km/h. The first airplane was in the air for 3 hours and traveled 2400 km, while the second airplane was in the air for 5 hours and traveled 4000 km.
