A Correct answer
Explanation

Time taken for 12 km at 4 km/hr is 12/4 = 3 hours. At 6 km/hr, distance covered in 3 hours is 6 * 3 = 18 km.

AI explanation

Using the formula time equals distance divided by speed, the person walks for 12 divided by 4, which is 3 hours. To find the new distance covered at 6 km/hr during this same time, we multiply the new speed by the time to get 6 multiplied by 3. This calculates to a distance of 18 km.
