To determine how far the ball will have traveled when it hits the ground, we need to solve the equation \( h(x) = 0 \), which means setting the height function to zero:

\[ 0 = -\frac{1}{30} x(x - 61) \]

To solve this, we can first simplify the equation. Since the function is multiplied by \(-\frac{1}{30}\), we can multiply both sides by \(-30\) (which will not change the equality) to eliminate the fraction:

\[ 0 = x(x - 61) \]

Next, we can factor this equation:

\[ 0 = x(x - 61) \]

Setting each factor equal to zero gives us:

  1. \( x = 0 \)
  2. \( x - 61 = 0 \) \(\Rightarrow x = 61\)

So, the solutions to the equation are \( x = 0 \) and \( x = 61 \).

The value \( x = 0 \) represents the point where the football is kicked (the starting point). The value \( x = 61 \) represents the horizontal distance traveled when the football hits the ground.

Thus, the ball will have traveled 61 yards before hitting the ground.
