Question 384036: in navigational terms, a minute is one sixtieth of a degree, and a second is one sixtieth of a minute. to the nearest foot, what is the length of a one-second arc on the equator? Answer by scott8148(6628) (Show Source):
You can put this solution on YOUR website! the circumference of the Earth is 40,000 km
(the original definition of a meter was the distance from the equator to the pole, divided by 10,000,000)
2.54 cm = 1 in.
4E9 cm * (1 in / 2.54 cm) * (1 ft / 12 in) = circumference in feet
divide the circumference by ___ 360º * (60 min / º) * (60 sec / min)
