The 'second' referred to is in reference to Degrees Minutes & Seconds Such As:
N 11°22'33" E (example) Where the 33" is the "Seconds".
However in the case listed above, the Degrees, minutes, and Seconds refers to a direction and not a location. The appropriate answer to the question refers to Latitude and Longitude, where you will express the degrees, minutes, and seconds as a location rather than a direction and will appear similar to this:
11°22'33" N, 11°22'33" W (example)
Answer in this scenario:
A degree covers about 69 miles. Divide that by minutes and find that there is about 1.15 miles in a minute. Divide that by 60 and you will find that there is about .019 miles in a second. Since there are 5280 feet in a mile, multiply .019 by 5280 to get about 101.20 feet in a second.
There are APPROXIMATLEY 101.20 FEET between two seconds of latitude or longitude.
