The mathematical composition model is as follows:

1 On Sunday, the family discussed Tomb-Sweeping Day's visit to his hometown. Chatting and chatting, a question suddenly popped up in my heart: How far is it from here to my hometown? I asked my mother, and she said with a smile, what do you think? You have studied for so many years, there must be a way to know, right?

I immediately picked up the map and found Taizhou City, but I couldn't find the Gaogu Town where my hometown was located. What shall we do? I thought hard and suddenly had a brainwave: I can find huangqiao town, the nearest town to my hometown Gaogu Town, and measure the distance from Taizhou to huangqiao town on the map, and then subtract some, which is the approximate distance from Taizhou to my hometown on the map.
