    Answer:

    340 seconds = 5.667 minutes

    Explanation:

    As we know, S = v t or t = S / v (S = 51 x 10^9 m and v = 3 x 10^8 ms^-1)

    So, t = 51 x 10^9 / 3 x 10^8 = 17 x 10^1 = 170 s

    For a RTT estimation, the time span will be doubled of one way propagation for transmission and receive delay.

    The over all round trip time will be = 170 x 2 = 340 seconds = 5.667 minutes
