What is the equivalent of 1°53' in time units?

Correct Answer: Option A — 7 min. 32 sec.

Applying the conversion factor where 15 degrees of arc equals 1 hour of time (or 1 minute of arc equals 4 seconds of time), multiply 53 minutes by 4 to get 212 seconds (3 minutes 32 seconds), and 1 degree by 4 minutes, totaling 7 minutes 32 seconds.
