ReportAnswer #1

Concept used - Aiming with the current sweeps her much farther downstream than aiming against the current

----------------------------------------------------------------------------

direction to cross the river in shortest time is H

--------------------------------------------------------------------------------

Boy will land on the opposite shore for direction C

-------------------------------------------------------------------------------------------

Time to row across for A is equal to for K

The distance traveled in crossing for B is less than for F

time to row across for A is more than for C

time to row across for J is less than K

For an observer on shore, the speed of boat for A is more than for C (not sure about this one)
