A bus traveled on the highway and on local roads to complete a trip of $160 \text{miles}$. The trip took $4 \text{hours}$. The bus traveled at an average speed of $55 \text{miles} \text{per} \text{hour} \left(\text{mph}\right)$ on the highway and an average speed of $25 \text{mph}$ on local roads. If $x$ is the time, in hours, the bus traveled on the highway and $y$ is the time, in hours, it traveled on local roads, which system of equations represents this situation?
