is answer 1 km?

(considered speed = 2 x 10^8)

Yes the answer they gave is, Was that the mistake in the question?
0

Yes,

At best the signals propagate (radiate) through free space at the speed of light (3 x 10^8 m/s). In contrast, the speed of propagation through twisted pair wire or coax is 2/3 of this value.

Q.Consider a network connecting two systems connected 2000 Km apart. The band width of the network is 70 Mbps. The propagation speed of the signal is 2 10 m/sec and average size of the frame is 10 KB. Assume processing delays at nodes are negligible. Selective repeat sliding window ... KB as 10 x 10^3 bits , how? it should be multiplied with 8 to convert frame to bits. correct me if i m wrong.

A token bucket scheme is used for traffic shaping. a new token is put into the bucket at every 10 micro second. assume each token pick one packet which contain 2B of data. it is observed that initial capacity of bucket is 10 Mb. the computer can transmit at full speed of 8 Mbps for ... ) = MT what is R? is it token arriving rate (0.1M/s) or data transmitted equivalent to token (16bits * 0.1M/s) ?
