    Answer And Explanation

    Answer: Option C

    Explanation:

    From the given question,
    we will first calculate the speed of train relative to man,
    => ( 60 + 6 ) = 66 km/hr ( we added 6 because man is running opposite )
    Convert it in metre/second
    \begin{aligned}
    = 66 \times\frac{5}{18} \\
    = \frac{55}{3} m/sec\\
    \text{Time it will take to pass man }\\
    = 110 \times \frac{3}{55} \\
    = 6 \text{ seconds}
    \end{aligned}
