  2. 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.
