Question

Вертолет преодолел расстояние 3150км за 7 ч. за сколько часов вертолет преодолеет это расстояние, если его скорость увеличится на 180 км/ч ? уровнение пожалуйста

Answer 1

х- время. х*(3150:7+180)=3150 х*630=3150 х=3150:630. х=5 ч

Answer 2

Problem Analysis

We are given that a helicopter traveled a distance of 3150 km in 7 hours. We need to determine how long it will take for the helicopter to cover the same distance if its speed increases by 180 km/h.

Solution

To solve this problem, we can use the formula:

Time = Distance / Speed

Let's denote the original speed of the helicopter as S km/h. According to the given information, the helicopter traveled a distance of 3150 km in 7 hours. Therefore, we can write the equation:

7 = 3150 / S

To find the new time when the speed increases by 180 km/h, we can use the same equation with the new speed denoted as S + 180 km/h:

Time = Distance / Speed = 3150 / (S + 180)

Let's solve this equation to find the new time.

Calculation

To find the new time, we substitute the value of S into the equation:

Time = 3150 / (S + 180)

Using the given information, we can solve for S:

7 = 3150 / S

Simplifying the equation, we have:

S = 3150 / 7

Calculating the value of S, we find:

S ≈ 450 km/h

Now, we can substitute the value of S into the equation for the new time:

Time = 3150 / (450 + 180)

Calculating the value of the new time, we find:

Time ≈ 3150 / 630

Time ≈ 5 hours

Answer

If the helicopter's speed increases by 180 km/h, it will take approximately 5 hours to cover a distance of 3150 km.

Equation

The equation used to solve this problem is:

Time = Distance / Speed

Where: - Time is the time taken to cover the distance, - Distance is the total distance covered, and - Speed is the speed of the helicopter.
