To answer that question takes a lot of “ifs.”
If the earth were completely dry, with no oceans separating continents, you, as a person, could walk around our planet, traveling day and night at a steady pace, in less than a year.
If, however, you were a tidal wave, you could cross the earth in 60 hours.
If you were a Boeing 747 jet and could fly nonstop around the earth, your trip would take about 44 hours.
If you were a speeding bullet, shot with enough force, you could make the trip in 14 hours.
If you were a beam of light, then your trip would take only 1/10 of a second.
