Total time of travel required for A & B to meet at a point = 
4 hr & dog will travel only for 4 hr (until A & B meet) to cover a distance = 12 × 4 = 48 km

Approach:
In this problem, we need to find the distance traveled by the dog before men A and B meet. We can solve this by finding the time taken for men A and B to meet and then calculating the distance traveled by the dog during this time.
Calculating time taken for men A and B to meet:
Let the time taken for men A and B to meet be T hours.
Distance traveled by A in T hours = 10T km
Distance traveled by B in T hours = 5T km
Total distance traveled by A and B = 10T + 5T = 15T km
Since the total distance between A and B is 60 km, we have:
15T = 60
T = 60/15
T = 4 hours
Calculating distance traveled by the dog:
During the 4 hours it took for men A and B to meet, the dog was running towards A and then towards B repeatedly.
Distance traveled by the dog in 1 hour = 12 km
Distance traveled by the dog in 4 hours = 12 * 4 = 48 km
Therefore, the distance traveled by the dog before men A and B meet is 48 km.
Therefore, the correct answer is option D) 48 km.
