    Given:

    • Aeroplane is flying at the height of 1600m
    • To land, it is descending its speed at the rate of 70m/minutes

    To Find:

    • How many time it will take to come to height of 200m

    Solution:

    In the question, it is given that an aeroplane is at the height of 1600 is descending downward at the rate of 70m/minutes and aeroplane is needed to come at the height of 200m.

    Therefore,

    • Aeroplane will cover total distance = 1600 – 200 = 1400m

    We know that :

    • \large{\boxed{\small{\bf{Time~=~\dfrac{Distance}{speed}}}}}

    Hence,

    Aeroplane will take time = \small{\bf{\dfrac{distance}{speed}}}

    → Aeroplane will take time = \small{\bf{\dfrac{1400}{70}}}

    → Aeroplane will take time = 20

    Therefore,

    • Aeroplane will take 20 minutes to come at the height of 200m.
