Yesterday your chronometer read 11h 59m 58s at the 1200 GMT time tick. Today your chronometer reads 12h 00m 00s at the 1200 time tick. What is the chronometer rate?
AI Explanation
The correct answer is D) +2s.
The chronometer rate is the difference in time between the chronometer reading and the actual time. In this case, the chronometer reading at the 1200 GMT time tick changed from 11h 59m 58s to 12h 00m 00s, indicating a change of +2 seconds. This means the chronometer is running +2 seconds fast compared to the actual time.
The other options are incorrect because:
A) Nil is incorrect as the chronometer is not running at the exact time.
B) -2s is incorrect as the chronometer is running fast, not slow.
C) 12h is incorrect as this is not the chronometer rate, but rather the time shown on the chronometer.
