Answer 2

Calculation of Distance from Home to Stadium

To calculate the distance from home to the stadium, we can use the formula:

Distance = Speed × Time

Let's calculate the distance using the given information:

- Walking speed: 4 km/h - Bicycling speed: 12 km/h

Since Sergey walks from home to the stadium at a speed of 4 km/h and one day he decided to ride a bicycle at a speed of 12 km/h, we can assume that the time taken to travel from home to the stadium remains the same in both cases.

Let's denote the distance from home to the stadium as "d".

When Sergey walks, the time taken to travel from home to the stadium can be calculated as:

Time = Distance / Walking Speed

When Sergey rides a bicycle, the time taken to travel from home to the stadium can be calculated as:

Time = Distance / Bicycling Speed

Since the time taken remains the same in both cases, we can equate the two equations:

Distance / Walking Speed = Distance / Bicycling Speed

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

Distance / 4 = Distance / 12

To solve this equation, we can cross-multiply:

12 × Distance = 4 × Distance

Simplifying the equation:

12d = 4d

8d = 0

Since the equation 8d = 0 implies that d = 0, it means that the distance from home to the stadium is 0 kilometers.

Therefore, the distance from home to the stadium is 0 kilometers.

Please note that the given information does not provide any specific time duration or additional details that could affect the calculation.
