Answer 2

Total is ~ 112865.83 m in 1° 1' 1"   for latitude

There are ~ 111 km in 1°

Degrees — 111 x 1000 = 111000 m

Minutes — 111000 / 60 = 1850 m

Seconds — 1850 / 60 = 30.83 m

Total is ~ 112865.83 m in 1° 1' 1"

Total is113207.27 m for 1° 1' 1" for Longitude (at the equator)

Longitude is basically the same at the equator ( a tiny bit more ) but changes as you move north and south since the distance between the degrees becomes less and less. I believe it is 111.321 km between longitude degrees which makes the total 113207.27 m for 1° 1' 1".

The Longitude is about 341.44 m longer at the equator than the Latitude distance is anywhere.

Answer 3

A meter is 1/10,000,000 the distance between the equator and North Pole.  In degrees, that's 90 degrees, or 5400 minutes (90 * 60) or 324,000 seconds.

324,000 seconds/10,000,000 meters = .0324 seconds/meter.

Answer 4

Each degree of latitude is approximately 111 kilometers apart.  Each minute (1/60th of a degree) is approximately 1.85 km.   Each second is approx. 30.8 meters.

A degree of longitude is widest at the equator at 111.321 km and gradually shrinks to zero at the poles. At 40° north or south the distance between a degree of longitude is 85 km.  Minutes are 1/60 of the degree.  Seconds are 1/60 of a minute.
