Answer 1

33÷3=11(км/ч)
ответ 11 км/ч

Answer 3

Problem Analysis

Two pedestrians leave a village simultaneously and walk in opposite directions. After 3 hours, the distance between them is 33 km. We need to find the speed of the second pedestrian.

Solution

Let's denote the speed of the first pedestrian as x km/h and the speed of the second pedestrian as y km/h.

After 3 hours, the first pedestrian has covered a distance of 3x km, and the second pedestrian has covered a distance of 3y km. The sum of these distances is equal to 33 km.

So, we have the equation: 3x + 3y = 33

To find the speed of the second pedestrian, we can solve for y in the given equation.

Calculation

We can solve the equation 3x + 3y = 33 for y: 3y = 33 - 3x y = (33 - 3x)/3

Substitution

We can substitute the value of x from the given snippets and calculate the value of y.

From Source we have: x = 32

Substituting x = 32 into the equation: y = (33 - 3*32)/3 y = (33 - 96)/3 y = -63/3 y = -21

Answer

The speed of the second pedestrian is -21 km/h. However, it's important to note that a negative speed doesn't make sense in this context. It's likely that there was an error in the given information or calculation.
