ASSUMING it takes the same time to measure each feature (seldom true) then, since it takes 24 hours to measure 198 features, it takes \(\displaystyle \frac{24}{198}= \frac{12}{99}\) hours to measure each feature and so will take \(\displaystyle \left(\frac{12}{99}\right)67\) hours to measure 67 features.
