To find the distance \( x \) the football travels before hitting the ground, we need to solve the equation
\[ 0 = -\frac{1}{30}x(x - 61) \]
First, we can factor this equation. Setting the equation equal to zero, we have:
\[ -\frac{1}{30}x(x - 61) = 0 \]
This equation equals zero if either \(-\frac{1}{30} = 0\) (which is not true) or if the product \(x(x - 61) = 0\).
From the product \(x(x - 61) = 0\), we can set each factor to zero:
- \(x = 0\)
- \(x - 61 = 0 \Rightarrow x = 61\)
Thus, the possible values of \(x\) are \(0\) and \(61\).
The ball will hit the ground when \(x = 61\) since \(x = 0\) represents the starting point of the kick off.
Therefore, the ball will have traveled
\[ \boxed{61} \]
yards before hitting the ground.
