Suppose a 1 gbps point-to-point link is being set up between the earth and a new lunar colony. the distance from the moon to earth is approximately 385,000 km, and data travels over the link at the speed of light (3 x 10⁸ meters per
calculate the minimum rtt (two-way propagation time) for the link.(in other words, how long would it take to send a single bit to the moon and immediately bounce it right back to earth? )
