seconds

Calculate Increase in Seconds: Calculate the increase in seconds based on the original time. $\newline$ Original time: $66$ seconds $\newline$ Increase: $50\%$ of $66$ $\newline$ Calculation: $0.50 \times 66 = 33$ seconds
Add to Find New Total: Add the increase to the original time to find the new total. $\newline$ Original time: $66$ seconds $\newline$ Increase: $33$ seconds $\newline$ New total time: $66 + 33 = 99$ seconds
