    Answer:

    15 seconds

    Step-by-step explanation:

    Thinking process:

    The time is given by the formula: t = \sqrt{\frac{h}{4} }

    The height h = 900

    then the time is given by: t = \sqrt{\frac{900}{4} } \\= 15 seconds

    Answer:

    7.5 seconds

    Step-by-step explanation:

    Using the formula

    t = \frac{\sqrt{h} }{4} ← substitute h = 900

    t = \frac{\sqrt{900} }{4} = \frac{30}{4} = 7.5
