You have a $10Mbps$ half$-$duplex Ethernet network that uses two communication cable

segments. In one cable of length $11,$ the signal speed is $v1={2\mathrm{.}5}^{***}{10}^{{?}^{{?}^{?}}}8\frac{m}{s}.$ In the second part of

the network, the signal speed is $v2={2\mathrm{.}0}^{**}{10}^{{?}^{{?}^{?}}}8\frac{m}{s}.$ What is the allowable length of the

second fragment to detect all collisions? There is no signal attenuation. ${}_4(10$ Puan$)$
