For the squeegee to pass by another window washer working at a height of 20 feet, it will take the squeegee 1.6 seconds.
<h3>Squeegee passage:</h3>
Using this model: h(t)= h0-16t²
Where:
h(t)=20
Let plug in the formula
60-16t²=20
-16t²=-40
t²=10÷4
t=±√10÷4
t=±√10÷2
t=3.16÷2
t=1.58 seconds
t=1.6 seconds (Approximately)
Inconclusion for the squeegee to pass by another window washer working at a height of 20 feet, it will take the squeegee 1.6 seconds.

To find the complex solutions of the equation we use the quadratic formula:
Therefore the solutions of the equation are:
Lets say,
40 + 55h = 190
40-40 + 55hh = 190 -40
55h = 150
55/55 = 150/55
~ 3.5 hours.
