none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.

you would 18 *0.25 = 4.5
