A man travelled from the village to the post office at the rate of 25 kmph and walked back at the rate of 4 kmph .
if the whole journey took 5 hours 48 minutes, then the distance of the post office from the village is:

A. 20 B. 22 C. 24 D. 26

• ANS :20
  avg speed = 2*4*25/(4+5) = 200/29
  again time is 29/5 hr
  hence distance = time *speed = 40 km
  distance of the post office from the village is is 40/2 = 20km
