Consider the following: city: Córdoba, Argentina
Longitude = 64 deg 10 min W
Latitude = 31 deg 28 min S
Time zone = GMT -3
Date = 01 August
On this date, the equation of time = -6 minutes. Assume no daylight saving time
(a) Determine the standard time at solar noon.
(b) Determine the hour angle at 8 AM standard time.
earth rotates 15degrees per hour
The Attempt at a Solution
15(3) = 45
64.1667 - 45 = 19.1667degrees.
if Earth rotates at 15Degrees per hour then that means for 19.1667degrees it needs to rotate about 1hour 17minutes.
thus standard time at solar noon is 12.00 - 1hour and 17 minutes + 6minutes
is that right so far?
using above answer, for part b i did the following:
from 8am to 11.49am there is 3hours 49 min difference.
(3 + 49/60) * 15 = 57.25degrees.
is that right?
