A bus traveled on the highway and on local roads to complete a trip of 160 miles. The trip took 4 hours. The bus traveled at an average speed of 55 miles per hour (mph) on the highway and an average speed of on local roads. If x is the time, in hours, the bus traveled on the highway and is the time, in hours, it traveled on local roads, which system of equations represents this situation?
A. 55x +25y = 4 ; x + y = 160
B. 55x +25y = 160 ; x + y = 4
C. 25x +55y = 4 ; x + y = 160
D. 25x +55y = 160 ; x + y = 4
