A man starts walking at 3 pm, He walks at a speed of 4 km/hr on level ground and at a speed of 3 km/hr on uphill, 6 km/hr downhill and then 4 km/hr on level ground to reach home at 9 pm. What is the distance covered on one way?	Answers:	A) 8	B) 9	C) 10	D) 11	E) 12
if x km is level ground and y km is hill road, then   x/4 + y/3 +y/6+x/4= 6   6(x+y)=72   x+y=12 km   so one side distance is 12 kms.   ANSW12R:12
