When a hot object is placed in a water bath whose temperature is $25^\circ \text{C}$, it cools from $100^\circ \text{C}$ to $50^\circ \text{C}$ in $160 \text{s}$. In another bath, the same cooling occurs in $140 \text{s}$. Find the temperature of the second bath.

The temperature of the second bath = ${}^\circ \text{C}$
