Hello
for minimum distance we have to travel right accross the river
=> resultant_horizontal speed =0
for minimum time we maxmize the perpendicular to river speed
=>resultant_horizontal speed = speed of the river.
in that case you have to travel some more distance to get to the point right across the river=v_river*t_taken
We won’t give you example because method is enough.
Thanks & Regards
