You can use #in available in Rails like this

irb(main)> Time.zone.now
=> Thu, 18 Jan 2024 20:26:35.035644801 UTC +00:00
irb(main)> Time.zone.now.in("10".to_i.minutes)
=> Thu, 18 Jan 2024 20:36:36.377030022 UTC +00:00

where "10" is the string from your parameter. I.e.

@presentation.date = @category.date.in(@addtime.to_i.minutes)

minutes isn't a method on String. You need to convert your param to a number first.

@presentation.date = @category.date + @addtime.to_f.minutes
