A man can ride on cycle at 35 kmph upward road and 70 kmph downward road. He takes 6 hours to cycle uphill from lower point A to upper point B and back to A. What is the total distance traveled by him in 6 hours? He must return back to base point A in remaining time  Choices:
A) 120
B) 140
C) 160
D) 280
E) 180
Upward distance traveled per hour - 35 km,   distance traveled after 4 hours = 140 km.   He remained with 2 hours travel downward, i.e. distance traveled in remaining 2 hours downward = 140 km   so total distance traveled from A to B and Back to point A = 140 km upward + 140 km downhill = 280 km   (Answer : 280)
