Solving a linear equation we conclude that the helicopter will take 4 minutes to reach the ground.

How long does it take to reach the ground?

We know that the equation that models the height of the helicopter is:

y = -300*x + 1200

Where y is the height and x is the time in minutes.

The helicopter will reach the ground when y = 0, then we need to solve:

0 = -300*x + 1200

Now we can solve this linear equation for x, it will give:

300*x = 1200

x = 1200/300 = 4

x = 4

Then, we conclude that the helicopter will take 4 minutes to reach the ground.
