i need help with this question i have an idea but i'm sure if i'm right if someone could lead me in the right directiion

2. Consider two hosts, A and B, connected by a single link of rate R bps. Suppose that the two hosts are separated by m meters, and suppose the propagation speed along the link is s meters/sec. Host A is to send a packet of size L bits to Host B. Express the propagation delay, dprop, in term of m and s Determine the transmission time of the packet, drans, in terms of L and R. Ignoring processing and queuing delays, obtain an expression for the end- a. b. c. to-end delay. d. Suppose dprop is greater than drans , At time dran, where is the first bit of the packet? Suppose s-2.5x108, L-120bits, and R-56 kbps. Find the distance m so that dprop equals drans e
