Question

Can someone help fill in the blanks? Thank you!

The following table shows the number of hours between sunrise and sunset for different locations on Earth on both solstices (June 21 & December 21) and equinoxes (March 21 & September 21).

Latitude	March 21	June 21	September 21	December 21
Equator	12	12:07	12	12:08
10° N	12	12:43	12	11:33
20° N	12	13:21	12	10:54
30° N	12	14:05	12	10:13
40° N	12	15:01	12	9:20
50° N	12	16:22	12	8:04
60° N	12	18:52	12	5:52
66° N	12	24	12	0

III)        For each city listed below, find its latitude, and using interpolation (finding an estimate of a value within two known values in the table above), predict the number of hours of daylight and darkness for each city. The first row and ‘March’ and ‘September’ columns are done for you. (0.25 points per entry = 3.75 points total)

City	Latitude	December 21 Daylight Darkness (times)	March 21 Daylight Darkness (times)	June 21 Daylight Darkness (times)	September 21 Daylight Darkness (times)
Portland, OR	45°	8:40 15:20	12 h 12 h	15:40 8:20	12 h 12 h
Phoenix, AZ	33°		12 h 12 h		12 h 12 h
Mexico City, DF	19°		12 h 12 h		12 h 12 h
Adelaide, Australia	-34°		12 h 12 h		12 h 12 h
Fairbanks, AK	64°		12 h 12 h		12 h 12 h
Iquitos, Peru	-3°		12 h 12 h		12 h 12 h
