First, we need to calculate the standard time for the task, which is equal to the average time plus a contingency allowance of 10% of the job time.

ST = AT + (AT*Contingency Allowance)
ST = 90 + (90*0.10)
ST = 99 seconds

Next, we need to calculate the time for the bartender if they worked 20% faster than average.

Time = Average Time / (1 + % Increase)
Time = 90 / (1 + 0.20)
Time = 75 seconds

Finally, we need to add the contingency allowance to the faster time to get the standard time at the faster pace.

ST Fast = Time + (Time*Contingency Allowance)
ST Fast = 75 + (75*0.10)
ST Fast = 82.5 seconds

Rounding up to the nearest 0.1 or 0.5, the answer is C) 118.8 seconds.
