Best answer 0 votes 0 votes Given that ethernet frame :we apply TT = 2 *PT data size / BW = 2 *( length / velocity) ( 1000 *8 ) / ( 5 mbps) = 2 * ( X / 3 * 108) X = 240000 = 240 KM Hradesh patel answered Jan 17, 2017 selected Jan 17, 2017 by vishwa ratna Hradesh patel comment Share Follow See all 0 reply Please log in or register to add a comment.
