Consider a 25 MHz noise-less channel between two nodes that are 100 km apart. Assume that we send 4 bits at a time. Assume that the speed of light is 2 108 meters/s. For calculation simplicity, we use 1 Mbps = 106 bps instead of 2 20bps. 5 pts each

(a) What is the length of one bit in time on this channel?

(b) What is the length of one bit in meters on this channel?

(d) How long does it take to transmit the packet over the 100 km distance from the time the first bit is transmitted to the time the last bit is received.
