Answer:
It would take approximately 8.82 sec for a penny to strike the person.
Step-by-step explanation:
Given:
Height of the building = 1250 feet
Height of the person = 6 feet.
Modeled equation is 
We need to find the time required 't' for the penny to strike the person.
Solution:
to find the time required 't' for the penny to strike the person we will substitute;
h ⇒ height of the person.
So we get;

Now Combining the like terms we get;

Dividing both side by 16 using division property we get;

Now taking square root on both side we get;

Hence It would take approximately 8.82 sec for a penny to strike the person.
