    Solution :

    Given ,

    • Distance = 7150 km
    • Speed = 780 km/h

    We need to find ,

    • Time taken = ?

    As we know that ,

    Speed = Distance/Time

    Simplifying ,

    Time = Distance/Speed

    Substituting ,

    • Distance = 7150 km
    • Speed = 780 km/h

    ⇒ Time = 7150/780

    Time = 9.166 h

    Hence , time taken by the body to travell 7150km with a speed of 780 km/h = 9.166 hrs

    • v = u + at
    • W = FS
    • P = F/A
    • F = m × a
    • S = ut + 1/2 at²
    • v² – u² = 2as
    • v² = – 2gH

    Answer:

    • Time taken = 9.167 hours

    Step-by-step explanation:

    Formula :

    Time = distance/speed

     \\  \\

    • then ,
    • Time = 7150/780 = 9.16666 ≈ 9.167 hours

     \\  \\

    • Time taken = 9.167 hours
