Quizplus · Accepted Answer

Absolute error is the difference between the estimated value and the actual value, which is $1\text{ hour } 23\text{ minutes} - 1\text{ hour } 8\text{ minutes} = 15\text{ minutes}$. Relative error is the absolute error divided by the actual value, $\frac{15\text{ minutes}}{68\text{ minutes}} \approx 22.1\%$.
