Question

(100 км/ч – 75 км/ч ) ⋅ x = 75 км

Answer 1

Пошаговое объяснение:

(100-75)×х=75

25×Х=75

Х=75:25

Х=3

Answer 2

Ответ: 3 часа

Пошаговое объяснение:

(100 км/ч – 75 км/ч ) ⋅ x = 75 км

25 км/ч · х = 75 км

х = 75 км : 25 км/ч

х = 3 ч

Answer 3

This looks like a math problem involving speed and time. The expression seems to represent the relative speed between two objects, and you're trying to find the time it takes for them to cover a certain distance. Let me help you break it down.

The expression is $(100 \, \text{km/h} - 75 \, \text{km/h}) \cdot x = 75 \, \text{km}$.

The term $(100 \, \text{km/h} - 75 \, \text{km/h})$ represents the relative speed, and $x$ is the time in hours. The product of these two gives you the distance traveled.

Now, let's set up the equation:

$(100 \, \text{km/h} - 75 \, \text{km/h}) \cdot x = 75 \, \text{km}$

Simplify the left side:

$25 \, \text{km/h} \cdot x = 75 \, \text{km}$

Now, solve for $x$ by dividing both sides by 25:

$x = \frac{75 \, \text{km}}{25 \, \text{km/h}}$

Simplify further:

$x = 3 \, \text{h}$

So, it would take 3 hours for the two objects to be 75 kilometers apart with a relative speed of $(100 \, \text{km/h} - 75 \, \text{km/h})$.
