A Correct answer
Explanation

Distance = speed * time. The car traveled for 3 hours at speed u, covering 3u km. It still needs to travel 15 km. Total distance = 3u + 15.

AI explanation

Using the formula distance equals speed multiplied by time, the distance covered by the car in 3 hours is u multiplied by 3, giving 3u km. Since Shaktinagar is still 15 km away, the total distance between the two cities is the sum of the distance covered and the distance remaining. Therefore, the total distance is 3u plus 15 km.
