Answer:
Light is moving at the speed = 77.78 km/min
Step-by-step explanation:
Given:
Distance between island and point P = 5 km
Moving along the the shoreline when it is 1 km from P.
So, x = 1
From the above statement light makes seven revolutions per minute.
Therefore,
Solution:
From the given figure.

Substitute x = 1
-------------------(1)
Now, first we differentiate both side with respect to t.

Using chain rule.



Substitute
from equation 1.


Substitute 

Applying cross multiplication rule.


Therefore, light is moving along the shore at the speed of 77.78 km/min
The formula for finding area of a rectangle is a=lw.
Write what is given
Area is 64.
Length if 16.
Width is unknown.
Therefore the equation would look like this:
64=16*w
Now to solve for w.
Divide 16 both sides.
64/16 is 4. Therefore:
w=4
