Two safety questions......

[dixiebreeze]

How many miles between degrees of longitude?

And, I have bottled and canned water (unopened) on hand since last September. Any chance it's gone bad? No dates on containers.

How many miles between degrees of longitude?

The number of miles between degrees of longitude decrease as you go north; i.e. 75.0°W to 76.0°W is (roughly) 65.5 miles.

One degree latitude is approximately 69 miles across the world.

Thank you, Coldfront

Someone told me the other day that bottled water does not go bad.

Thanks, zoeyann, I just found the answer:

Water, bottled 1-2 years Refrigerate open jars.

Perfectly correct answer.

Most bottled water now has an use by date. It can be ignored. Consider it an insurance clause for the manufacturer.

Thanks Dixie, guess I shouldn't take too much expiration date info from that friend anymore

The expiration has to do with the degrading of the container which is plastic and probably has petroleum by products. I seem to remember reading about this last year.

The definition of a nautical mile is on minute of the circumference of the earth. 60 minutes = 1 degree, or 60 nautical miles.

Note that the distance between degrees of longitude shrinks as you move away from the equator toward the poles, while one degree of change in latitude north or south is always 60 nautical miles anywhere on earth.

Some rough conversion numbers you can use:

Just like 1 knot = 1.15 mph, 1 nautical mile = 1.15 statute miles.

Thus one degree of change in longitude at the equator = 60 nautical miles or 60 x 1.5 = 69 statute miles.

Here are rough calculations for distances of one degree of longitude at intervals from the equator, north or south to the poles:

Latitude / Nautical Miles / Statute Miles

00 / 60.00 / 69.00
05 / 59.77 / 68.74
10 / 59.09 / 67.95
15 / 57.96 / 66.65
20 / 56.38 / 64.84
25 / 54.38 / 62.54
30 / 51.96 / 59.76
35 / 49.15 / 56.52
40 / 45.96 / 52.86
45 / 42.43 / 48.79
50 / 38.57 / 44.35
55 / 34.41 / 39.58
60 / 30.00 / 34.50
65 / 25.36 / 29.16
70 / 20.52 / 23.60
75 / 15.53 / 17.86
80 / 10.42 / 11.98
85 / 05.23 / 06.01


Hope that helps...
