SQL to find all rows with the highest number value

Hello, I am having some trouble coming up with a SQL statement that will give me the results that I need and was hoping yall could help


given a table like:

ID  Day/Time                instance
1   Monday 10:00       1
2   Tuesday 10:00       1
3   Tuesday  12:00      2
4   Tuesday  18:00      3
5   Wednesday 9:00   1          


How can I query all values on the same day with only the highest instance number? so that i return something like:


ID  Day/Time                instance
1   Monday 10:00       1
4   Tuesday  18:00      3
5   Wednesday 9:00   1    


Thank you very much for taking a look and any help you can provide.
