understandable

1)翻译下面的句子

今天路上太堵了，迟到几分钟没事

It's a understandable  late  for minutes for the bad traffic jam today.

2)结合自己的生活、学习、工作、兴趣等，想象在什么语境下会用到这个表达。先简要描述这个场景，再造句。

场景:我高考数学考得不及格可以理解,因为当年的题目太难了

造句:That I failed in my math entrance examination to college was understandable  becsuse the questions were too difficult.
