Answer 2

Problem Analysis

Andrey is traveling from a village to a city by car at a speed of 55 km/h. The journey takes him 2 hours. He then returns from the city to the village on the same road, but this time on a moped at a speed of 22 km/h. We need to calculate how long it will take Andrey to reach the village.

Solution

To find the time it takes for Andrey to reach the village, we can use the formula:

Time = Distance / Speed

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

Calculation

The distance between the village and the city is the same for both trips. Let's assume this distance is D.

For the first trip by car: - Speed = 55 km/h - Time = 2 hours

Using the formula, we can calculate the distance: D = Speed * Time

For the second trip by moped: - Speed = 22 km/h - Time = ?

Using the formula, we can calculate the time: Time = D / Speed

Since the distance is the same for both trips, we can equate the two formulas:

Speed * Time = D = 55 km/h * 2 hours

Now we can solve for the time it takes for Andrey to reach the village by moped:

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

Let's calculate the result.

Calculation Result

To find the time it takes for Andrey to reach the village by moped, we can substitute the values into the formula:

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

Simplifying the expression:

Time = 110 km/h / 22 km/h = 5 hours

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

Answer

Andrey will reach the village in 5 hours when traveling by moped at a speed of 22 km/h.
