You are taking a time tick using the 1200 signal from Valparaiso, Chile. You hear a series of 1 second dashes followed by a 9 second silent period, then a long 1.3 second dash. At the beginning of the long dash, your comparing watch reads 12h 00m 18s. When compared to the chronometer, the comparing watch reads 12h 01m 23s, and the chronometer reads 11h 59m 35s. What is the chronometer error?

Question

Accepted Answer

Option B: 1m 30s slow. Chronometer error is the difference between the chronometer time and the signal time. The watch reads 12:00:18 at the signal, while the chronometer reads 11:59:35, making it 43 seconds slow relative to the watch. Since the watch is 47 seconds slow relative to the chronometer, the total error is 1m 30s slow.
