Time and a half is 1.5× your regular hourly rate. It's the standard FLSA overtime premium for any hour worked beyond forty in a workweek.

At your regular rate, those 10.0 hours would have paid $220.00. The 1.5× premium adds $110.00 on top.
Under the FLSA, non-exempt employees must receive 1.5× pay for every hour worked beyond 40 in a single workweek. California, Alaska, and Nevada additionally require 1.5× after 8 hours in a single day. Holiday pay at 1.5× is not federally required, but is a common employer policy.
