Question

Помогите, пожалуйста! Скорость вертолёта в 5 раз больше скорости автомашины. Вертолёт за 2 часа пролетел на 480 км больше, чем автомашина проехала за это же время. Найдите скорость вертолёта. Если можно помогите решить не через икс. Заранее спасибо.

Answer 1

х - скорость машины

5х - скорость вертолета

2*5х - 2*х = 480

8х = 480

х = 60 - скорость машины

скорость вертолета равна 5х = 5*60 = 300 (км/ч)

 

Answer 2

Problem Analysis

We are given that the speed of a helicopter is 5 times greater than the speed of a car. The helicopter traveled 480 km more than the car in 2 hours. We need to find the speed of the helicopter.

Solution

Let's assume the speed of the car is x km/h. Since the speed of the helicopter is 5 times greater, the speed of the helicopter is 5x km/h.

We are given that the helicopter traveled 480 km more than the car in 2 hours. We can set up the following equation to represent this information:

Distance traveled by the helicopter = Distance traveled by the car + 480 km

Using the formula distance = speed × time, we can write the equation as:

(5x) × 2 = x × 2 + 480

Simplifying the equation:

10x = 2x + 480

8x = 480

x = 60

Therefore, the speed of the car is 60 km/h, and the speed of the helicopter is 5 times greater, which is 5 × 60 = 300 km/h.

So, the speed of the helicopter is 300 km/h.

Answer

The speed of the helicopter is 300 km/h.
