Explanation
Use D = RT:
Distance = \(x(2x)\)
Distance = \(2x^2\)
Which is greater, 2x2 or 3x? If x = 1, then 3x is greater.
But if x = 2, then 2x2 is greater.
Without information about the value of x, the relationship cannot be determined.

r = 2x*x which is = 2x^2
x could be anything so the answer d
x could be anything so the answer d
