Seoyoon traveled by train that goes 120 kilometers (km) per hour to get from her house to her grandmother's house. After traveling for 2 hours by train, the remaining distance to her grandmother's house was 2.4 kilometers (km). If it took 3 hours by car to go from Seoyoon's house to grandmother's house at a constant speed, how many kilometers (km) does the car travel per hour?
120 2 [OP_MUL] 2.4 [OP_ADD] 3 [OP_DIV]
