Answer:
The tip of her shadow is moving at the speed of 9.66 ft/sec
Explanation:The height of the street light = 19 feet
The height of the woman = 5.25 feet
Distance between the woman and the base of the pole, x = 35 ft
The speed of the woman towards the pole, dx/dt = 7ft/sec
The distance from the base of the streetlight to the tip of the woman's shadow = y
The distance from the woman to the tip of her shadow = y - x
The diagram illustrating this description is shown below
Using similar triangle:
Find the derivative of both sides with respect to time, t
The tip of her shadow is moving at the speed of 9.66 ft/sec
