A boat goes 96 km upstream in 8 hours and covers the same distance moving downstream in 6 hours. On the next day it starts from point A, goes downstream for 1 hour, then upstream for 1 hour, and repeats this for four more times, that is, 5 upstream and 5 downstream journeys. Then the boat would be

A

22.5 km downstream of A

B

20 km downstream of A

C

15 km downstream of A

D

12.5 km downstream of A
