Question

What is 42° 15' 5" in in decimal degrees?

Answer 1

this one isn't too bad if you understand this idea:
' means minutes, so 60 minutes = 1 degree and
"" means seconds, so 60 seconds = 1 minute

so start with the last number first, 5"
so 5/60 = 0.08333
which is now the same as saying
42degrees 15.083333 minutes
make sense?

Answer 2

\[42+\frac{15}{60}+\frac{5}{3600}=\frac{30421}{720}=42.2514 \]

Answer 3

Thanks!
