A person plans to row a boat from point A on one side of a straight river to a point B on the other side, as shown. All distances are measured in feet. rowacross Suppose the river is 300 feet wide and the person can row at a speed of 5 feet per second. Express the time needed for the person to row from point A to point B as a function of x.

Step-by-step explanation:

Express" (and any subsequent words) was ignored because we limit queries to 32 words.

Here V

R

= velocity of river

V

M

= velocity of man in still water = 2m/s (given)

from figure it is clear that

sinθ=

V

M

V

R

, where θ=60 degree

⟹V

R

=

3

m/s

from figure it is evident that

V

M

cosθ×t=1000m

⟹t=1000 s
