Need serious help please!

Consider the figure below, in which a single router is transmitting packets, each of length L-bits, over a single link with transmission rate R-Mbps to another router at the other end of the link. Suppose that the packet length is L = 16000 bits, and that the link transmission rate along the link to router on the right is R = 100 Mbps. Replace the value of L by student_ID modulus 100. a) What is the transmission delay (the time needed to transmit all of a packet's bits into the link)? b) What is the maximum number of packets per second that can be transmitted by the link?

L:packet length (in bits) R: link transmission rates (Mbits/sec) Queue of packets waiting for output link
