How many total minutes are there in (25^\circ30')?
Advertisement
Answer and explanation
Correct answer: \(1530'\)
There are 60 minutes in 1 degree. Thus, \(25^\circ=25\times60'=1500'\); adding the remaining \(30'\) gives \(1500'+30'=1530'\). \(1500'\) represents only 25 degrees and does not include the extra 30 minutes. Exam tip: To convert a mixed angle into minutes, multiply the degrees by 60 and then add the minutes.
