Problem Analysis

We are given that the distance from the city to the village is 32 km, and the cyclist traveled this distance in 3 hours. In the first hour, the cyclist traveled 3/8 of the distance, and in the second hour, the cyclist traveled 1/4 of the distance. We need to determine how many kilometers the cyclist traveled in the third hour.

Solution

To find the distance traveled in the third hour, we need to subtract the distances traveled in the first and second hours from the total distance.

Let's calculate the distances traveled in the first and second hours:

- Distance traveled in the first hour: (3/8) * 32 km = 12 km - Distance traveled in the second hour: (1/4) * 32 km = 8 km

Now, let's calculate the distance traveled in the third hour:

- Distance traveled in the third hour: Total distance - Distance traveled in the first hour - Distance traveled in the second hour

Substituting the values:

- Distance traveled in the third hour: 32 km - 12 km - 8 km = 12 km

Therefore, the cyclist traveled 12 km in the third hour.

Answer

The cyclist traveled 12 km in the third hour.
