The owner of Touchdown Sports Bar wants to develop a time standard for the task of mixing a specialty cocktail. In a preliminary study, he observed one of his bartenders perform this task seven times with an average of $90$ seconds and a standard deviation of $5$ seconds.

What is the standard time for this task if the bartender worked at a $20$ percent faster pace than is average, and an allowance of $10$ percent of job time is used?
