Two metal wires A and B of lengths 80 cm and 120 cm respectively having equal cross-sectional area are connected to form a long wire. When the combination is subjected to a tension, the elongations of the wires A and B are 0.8 mm and 1.5 mm respectively. If the Young's modulus of the material of wire A is $1.6\times10^{11}\text{ Nm}^{-2}$, then the Young's modulus of the material of wire B (in $10^{11}\text{ Nm}^{-2}$) is:
