Consider the network shown below, with two senders $($A$,$B$)$ on the left, sending packets to two different

receivers $($C$,$D$)$ on the right. Each sender is sending packets to its receivers over a separate connection.

The links have transmission rates of R$1=100$ Mbps $($i$.$e$.,100$ x $106$ bits per second$)$ and R$2=150$

Mbps$.$ Suppose each packet is $1$ Mbit $(106$ bits$)$ in size. Assume that the propagation delay is $10$ msec per link. Note that each of the two sessions has a $3-$hop path from source to destination.What is the end$-$to$-$end delay of a packet from when it first begins transmission at a sender$,$ untilit is received in full by a receiver at the right. Assume store$-$and forward packet transmission. You can also assume the queueing delay is zero.
