I think a good typing speed if you need to type a lot would be ideally 80 wpm and minimum 60 wpm. Anything lower than 60 and you'd struggle typing longer texts. I suggest you try TypeRacer - the global typing competition or simply practice touch typing on one of the free typing softwares.
If you're trying to figure out how many words per minute you can read, once again, your best bet is generally to use an online speed reading test program. These are a little less common than typing speed tests but plenty of good ones can still be found with search engine queries like reading words per minute..
