Answer:
400 ft
Step-by-step explanation:
The building's shadow is 10 times the length of the flagpole's shadow. Since the shadow length is proportional to the object height, the building must be 10 times the height of the flagpole, so is 400 ft tall.
Instantaneous velocity represents the velocity at a particular point.
The instantaneous velocity at t = 3 is 7.7 ft/s
The table is given as:
![\left[\begin{array}{cccccccc}t&0&1&2&3&4&5&6\\s&0&4.9&10.7&23.2&50.4&109.4&237.8\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccccccc%7Dt%260%261%262%263%264%265%266%5C%5Cs%260%264.9%2610.7%2623.2%2650.4%26109.4%26237.8%5Cend%7Barray%7D%5Cright%5D)
To calculate the instantaneous velocity at 
We get the distance at 
At
, the distance (s) is:

So, the instantaneous velocity (v) is:

This gives

Divide 23.2 by 3

Hence, the instantaneous velocity at t = 3 is 7.7 ft/s
