Answer:
The time that the rocket will hit the ground will be:
Step-by-step explanation:
Given the expression

Here:
- x represents the time in seconds
- y represents the height of the rocket
We know that when the rocket will hit the ground, the height will get y = 0
i.e.

solving for x to determine the time that the rocket takes when it will hit the ground.
so

subtract 110 from both sides


Divide both sides by -16







solving


x = 17.40 seconds
also solving


x = -0.40 seconds
As time can not be negative.
Thus, the value of x = 17.40 seconds
Therefore, the time that the rocket will hit the ground will be:
3105605.46427
