<span>3x+3 is my calculated answer!</span>
The plant was 3 and a half inches.
It's either a (the first one) or b (the second one), but if I had to choose I would choose b. If I'm wrong I'm so sorry I spent 10 minutes looking at this.
Answer:

Step-by-step explanation:
Given
--- acceleration
--- final velocity
--- initial velocity (it is 0, because the car starts from rest)
Required
Determine the time taken
This will be solved using Newton's first equation of motion:

Substitute values for v, u and a



Make t the subject


<em>Hence, the time taken is approximately 5.2 seconds</em>
