If a man walks at a rate of 10kmph, he misses a train by 14minutes. However, if he walks at the rate of 12kmph, he reaches the station 10minutes before the arrival of the train. Find the distance covered by him to reach the station.	Choose the most appropriate option.
A) 6 KM
B) 15
C) 12
D) 4
E) 8
Let the required distance x km   difference in the times taken at two speeds = 12min = 1/5 hr   (x/10)-(x/12) = 1/10   x = 6   the required distance is 6 km   6 KMnswer is 6 KM
