The correct answer is A) 7 min. 32 sec. To convert 1°53' from degrees to time units, we use the following conversion: 1 degree = 4 minutes 1 minute = 60 seconds Therefore, 1°53' is equivalent to 1 degree + 53 minutes, which is 1 degree + (53 / 60) hours. Calculating this, we get 1 degree + 0.883 hours = 7 minutes and 32 seconds. The other answer choices are incorrect because they do not accurately convert the 1°53' value to the equivalent time units.
