A man can paddle a canoe at 3.2 m/s in still water.
He is canoeing in a river where the current is flowing 2.8 m/s south.
Find his speed if he paddles
(a) upstream in the north direction,
(b) downstream in the south direction,
(c) across the river in the east direction, and
(d) across the river in the west direction.
~~~~~~~~~~~~~~~~~~~~~~~
(a) 3.2 m/s - 2.8 = 0.4 m/s. ANSWER
(b) 3.2 m/s + 2.8 = 6.0 m/s. ANSWER
(c) = = 4.25 m/s (approximately). ANSWER
(d) = = 4.25 m/s (approximately). (same as in (c)) ANSWER
Solved.
