A person on foot could walk 700 meters in less than nine minutes at a speed of 3.1 miles per hour, which is a fairly slow walking pace. At a faster pace, such as about 6 mph, a person could walk it in less than five minutes.
Seven hundred meters is a little more than the length of six football fields, equal to 765.53 yards (a standard football field is 120 yards long). Seven hundred meters also equals 2,296 feet. Since 1 mile is 5,280 feet, 700 meters is less than half a mile, actually about two-fifths of a mile.
