Please answer three math questions, thank you! 1: The school bought 6 desks and 12 chairs for a total of 1176 yuan. It is known that the price of each desk is equal to that of six chairs. How much is the cost of each desk? 2: After Xiaohong gives Xiaoming 4.8 yuan, Xiaohong's money is 1.2 yuan less than Xiaoming's. how much more is Xiaohong than Xiaoming? 3: Xiaoqiang and Xiaohong are neighbors, and they are in the same school. Xiaohong has to walk 10 minutes to go to school. Xiaoqiang walks 30 meters more every minute than Xiaohong, so it takes 2 minutes less than Xiaohong. Their home is kilometers away from the school

6x6 + 12 = 48 (sheet) 1176 / 48 = 24.5 (yuan) 24.5x6 = 147 (yuan)
4.8 + 4.8-1.2 = 8.4 (yuan)
30x8 / (10-8) X10 = 1200 (km)
