Question 739Navigation General

The correct answer is C) -2s. The chronometer rate is determined by the change in the chronometer's time reading between two consecutive 1500 GMT time ticks. Yesterday, the chronometer read 03h 01m 56s at the 1500 GMT time tick, and today it read 03h 01m 54s at the 1500 GMT time tick. The difference between these two readings is -2 seconds, indicating that the chronometer is running -2 seconds slow. The other options are incorrect because: A) 2s fast - This would mean the chronometer is reading 2 seconds ahead, which is the opposite of the observed change. B) +2s - This would indicate the chronometer is running +2 seconds fast, which is also incorrect based on the observed change. D) 1m 54s fast - This is too large of a change to be the chronometer rate, as the observed change was only 2 seconds.
