Lets get started :)
We need to isolate t from x =

at²
Take 2 to the left-hand side { Do multiplication since you see division }
2x = at²
Take a to the left-hand side { Do division since you see multiplication }

= t²
Take square root since t is to the power of 2

= t
1,831 centimeters
Just multiply the number of meters by 100 to get your answer
ANSWER
4 roots.
EXPLANATION
The given polynomial function is

This is a fourth degree polynomial.
According to the Fundamental Theorem of Algebra, an nth degree polynomial has n roots.
This roots include both real and complex roots.
Also repeated roots or roots with multiplicity greater than one are counted as distinct.
Since the given polynomial function is a fourth degree polynomial, the Fundamental Theorem of Algebra, says that this polynomial has 4 roots.
