Question

A river is flowing from west to east at a speed of 5 meters per minute. a man on the south bank of the river, capable of swimming at 10 meters per minute in still water, wants to swim across the river in the shortest time. he should swim in a direction

Answer 1

Answer:

North West direction

Explanation:

d{ u-vsin(teta) }=zero

u-river velocity

v-man velocity

{to get shortest time drift distance is zero }

then sin(teta)=u÷v

for shortest time he has to swim in North West direction
