Calculation

To calculate the average speed at which the dacha owner needs to travel to reach the nearest train station in time, we can use the formula:

Average Speed = Total Distance / Time

In this case, the total distance is 2 km, and the time available is 30 minutes (or 0.5 hours). Let's calculate the average speed:

Average Speed = 2 km / 0.5 hours

To simplify the calculation, we can convert 0.5 hours to minutes:

Average Speed = 2 km / 30 minutes

Now we can calculate the average speed:

Average Speed = 2 km / 30 minutes = 0.067 km/minute

Therefore, the dacha owner needs to travel at an average speed of 0.067 km/minute to reach the nearest train station in time.

To represent the average speed of the dacha owner, we can use the letter U.

U = 0.067 km/minute

So, the answer can be written as:

U > 0.067 km/minute
