You are taking a time tick using the 1930 signal from Rio de Janeiro, Brazil. You hear the preparatory signal "CQ DE PPE" repeated several times followed by a short dash (0.4 sec), 60 dots (0.1 sec each) and another short dash. At the beginning of the last dash, the comparing watch reads 07h 30m 13s. When compared to the chronometer, the comparing watch reads 07h 31m 56s, and the chronometer reads 07h 30m 21s. What is the chronometer error?

Question

Accepted Answer

Option B: 1m 22s slow. Chronometer error is the difference between the chronometer time and the signal time. The watch reads 07:30:13 at the signal, while the chronometer reads 07:30:21, making it 8 seconds fast relative to the watch. Since the watch is 1 minute 30 seconds slow relative to the chronometer, the total error is 1m 22s slow.
