## Homework Statement

Given:

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.

## Homework Equations

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

= 11.49am

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?
