A man travels a certain distance at 12 km/h and returns to the starting point at 9 km/h. The total time taken by him for the entire journey 2 (1/3) hours. The total distance (in km) covered by him is:
According to question x/12 + x/9 = 7/3 LCM of 12 and 9 is = 36 3x+4x / 36 = 7/3 7x / 36 = 7/3 X = 7 × 36 / 3 × 7 X = 12km So Distance= 12km He travelled again to starting point hence = 12 × 2 = 24km
