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.
