Problem Analysis

We are given that a cyclist traveled from a city to a country house at a speed of 16 km/h and it took him 3 hours. On the return trip, he covered the same distance in 4 hours. We need to find the speed at which the cyclist traveled in the city.

Solution

Let's assume the distance between the city and the country house is d kilometers. We know that the cyclist traveled at a speed of 16 km/h and it took him 3 hours to cover the distance. Using the formula speed = distance / time, we can calculate the distance as follows:

d = speed × time = 16 km/h × 3 hours = 48 km.

On the return trip, the cyclist covered the same distance of 48 km in 4 hours. Again, using the formula speed = distance / time, we can calculate the speed as follows:

speed = distance / time = 48 km / 4 hours = 12 km/h.

Therefore, the cyclist traveled at a speed of 12 km/h in the city.

Answer

The cyclist traveled at a speed of 12 km/h in the city.
