Suppose nodes A and B are on the same $10$ Mbps Ethernet segment and the propagation delay between$$ the two nodes is $225$ bit times. Suppose A and B send frames at the same time, the frames collide, and$$ then A and B choose their own values of K in the CSMA$/$CD algorithm. Assuming no other nodes are$$ active, can retransmissions from A and B collide. For our purposes, it suffices to work out the following$$ example. Suppose A and B begin transmission at t$=0$ bit times. They both detect collisions at t$=225$ bit$$ times. They finish transmitting a jam signal at t$=225+48=273$ bit times. Suppose KA$=1$ and KB$=0.$

Hints: Note that the random backoff component of scheduling delay is K$*512$ bit times. $$ Also note that the minimum Ethernet frame size is $512$ bits.$$
