A river \( 2 \mathrm{~km} \) wide is flows at the rate of \( 2 \mathrm{~km} / \mathrm{hr} \). A boatman who can row a boat at a speed of \( 4 \mathrm{~km} / \mathrm{hr} \) in
P
still water, goes a distance of \( 2 \mathrm{~km} \) upstream and then
W
comes back. The time taken by him to complete his journey is:
(1) \( 60 \mathrm{~min} \)
(2) \( 70 \mathrm{~min} \)
(3) \( 80 \mathrm{~min} \)
(4) \( 90 \mathrm{~min} \)
