The task that was completed in 1.16 hours versus the estimated 6.66 hours can be analyzed as follows:

1. Difference in Time: The difference between the actual and estimated time is: $6.66 - 1.16 = 5.5 \text{ hours}$ This means the task was completed 5.5 hours faster than expected.

2. Percentage of Actual Time Compared to Estimated Time: To find the percentage of time the task took compared to the estimated time: $\frac{1.16}{6.66} \times 100 = 17.42\%$ So, the task took approximately 17.42% of the estimated time.

3. Efficiency: To measure efficiency, you can compare the ratio of the estimated time to the actual time: $\frac{6.66}{1.16} \approx 5.74$ This indicates the task was done about 5.74 times faster than estimated.

Tip:

When estimating time for tasks, consider adding a buffer for unforeseen efficiencies or delays to improve accuracy.
