Answer
Explanation
First, we need to convert the 48'' into minutes. Using the conversion factor: 1' = 60'', we get:

Then, 14 minutes and 48 seconds are equivalent to 14 + 0.8 = 14.8 minutes. To convert this amount of minutes into degrees we need to use the conversion factor 1° = 60', as follows:
![\begin{gathered} 14.8^(\prime)=14.8^(\prime)\cdot(1\degree)/(60^(\prime)^(\prime)) \\ 14.8^(\prime)=(14.8)/(60)\degree \\ 14.8^(\prime)=0.247\operatorname{\degree} \end{gathered}]()
In consequence, 6° 14’ 48’’ is equivalent to 6 + 0.247 = 6.247°
