Answer:

12 seconds

Step-by-step explanation:

Given

y = -2.5x + 30

Required

Determine the time taken to reach the ground

For the paper to reach the ground, y = 0

So, we have:

y = -2.5x + 30

0 = -2.5x + 30

Collect Like Terms

2.5x +0 = 30

2.5x = 30

Divide through by 2.5

2.5x/2.5 = 30/2.5

x = 30/2.5

x = 12

<em>Hence:</em>

<em>Time taken is 12 seconds</em>
