Suppose nodes A and B are on the same $10$ Mbps broadcast channel, and the propagation delay between the two nodes is $225$ bit times. Suppose CSMA$/$CD and Ethernet packets are used for this broadcast channel. Suppose node A begins transmitting a frame and, before it finishes, node B begins transmitting a frame. Will this system work for CSMA$/$CD$?$ Why or why not?

Hint: Suppose at time t $=0$ bits, A begins transmitting a frame. In the worst case, A transmits a minimum$-$sized frame of $512$ bit times. So A would finish transmitting the frame at t $=512$ bit times. In the worst case, if collison happens, when does the jamming signal reach A$?$
