The Chinese class is in 9:00 am to 9:45 am为什么不用in？

一道英语问题~

1.His school bag is as big as mine.
2.Tom draws worse than Jack.
3.My elder brother is taller than me.
4.I run faster than him.
5.Which is easier,.......
6...... is the longest rivier in China.
7......sings best.....
8........the hardest subject.
9.which is the heaviest......
10....thinner than me.
11.We often share the lunch.
12.He often goes out on Thursday.
13.They often walked to school last year.
14.He is never late for school.
15/She smiles all the time( 最后一句怪怪的)

问题英文

在英语中表示短暂时间的介词用at，如: at 9:00 (在九点钟)，at noon (在正午)，而介词 in是表示较长时间，如: in March (在三月)，in 2020(在2020年)，但是本句中由于出现 to 9:45 (到九点四十五)，所以应该是 from 9:00 am to 9:45(从九点钟到九点四十五)。

The Chinese class is from 9:00 am to 9:45 am. 语文课是从早上9点到9点45分。
从……到……
用in意思不合适。

am应该是上午的意思，in没法用吧
