All the way around the Earth = 360 degrees
(360 degrees) x (60 minutes/degree) x (60 seconds/minute)
= 1,296,000 seconds
All the way around the Earth = 1,296,000 seconds of angle
But all the way around the Earth = about 25,000 miles
Each mile = 5,280 feet
All the way around the Earth = (about 25,000 miles)x(5,280 feet/mile)
= about 132,000,000 feet
So each second of angle = (about 132,000,000 feet) / (1,296,000)
That's (about 101.85 feet).
Which is pretty durn close to "Around 100 feet". (choice-A)
