Answer:
Explanation:
height of pole = 15 ft
height of man = 6 ft
Let the length of shadow is y .
According to the diagram
Let at any time the distance of man is x.
The two triangles are similar
![\frac{y-x}{y}=\frac{6}{15}](https://tex.z-dn.net/?f=%5Cfrac%7By-x%7D%7By%7D%3D%5Cfrac%7B6%7D%7B15%7D)
15 y - 15 x = 6 y
9 y = 15 x
![y=\frac{5}{3}x](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%7D%7B3%7Dx)
Differentiate with respect to time.
![\frac{dy}{dt}=\frac{5}{3}\frac{dx}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdt%7D%3D%5Cfrac%7B5%7D%7B3%7D%5Cfrac%7Bdx%7D%7Bdt%7D)
As given, dx/dt = 4 ft/s
![\frac{dy}{dt}=\frac{5}{3}\times 4](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdt%7D%3D%5Cfrac%7B5%7D%7B3%7D%5Ctimes%204)
ft/s
Yes it does.
