There are three classrooms (A, B, and C) in a building at a university. They can each fit into any of three spaces (S1, S2, and S3). The distance from S1-S2 is 40 meters, S2-S3 is 58 meters, and S1-S3 is 49 meters. The flow matrix (trips per day) between the classrooms is as follows. Classroom A Classroom B Classroom C Classroom A 60 71 Classroom B 42 0 Classroom C 0 50 If Classroom A is assigned to Space S3, Classroom B to Space S1, and Classroom C to Space S2, then the total distance travelled per day would be ? Calculate the answer
