Answer 3

Problem Analysis

To solve this problem, we need to find the time it takes for Andrey to travel from the city to the village. We are given that Andrey traveled from the village to the city at a speed of 55 km/h and it took him 2 hours. Then, he traveled back from the city to the village at a speed of 22 km/h. We need to determine the time it takes for him to reach the village.

Solution

Let's calculate the distance between the city and the village using the formula:

Distance = Speed * Time

We know that the distance is the same for both trips, so we can set up the equation:

55 km/h * 2 hours = 22 km/h * Time

Now, let's solve for Time:

Time = (55 km/h * 2 hours) / 22 km/h

Calculating this expression will give us the time it takes for Andrey to reach the village.

Calculation

Let's calculate the time it takes for Andrey to reach the village:

Time = (55 km/h * 2 hours) / 22 km/h

Time = 110 km/h / 22 km/h

Time = 5 hours

Therefore, it will take Andrey 5 hours to reach the village.

Answer

Andrey will reach the village in 5 hours.
