it depends on where you go around the world (and depending on if you count the axises) ... for example, walking around the world at the Northern pole at a circumference of 20 miles would take you an hour to circle the earth going around it's axis... walking around the Northern pole at a few feet circumference would take you a couple seconds.... but if you don't count that as going around the world and you're thinking the full circumference of the Earth... then that would be about 24,901.55 miles/ 20mph = 1245.0775 hours going around the equator.. and about 24,859.82 miles/20mph =1242.991 hours going around its axis (Meridional)

Technically it depends upon where you do the walking. In one sense you can go over every line of longitude i.e. "around the world", in a few steps at either Pole--just walk around in a circle. Most of the time, a question means around the circumference of the planet which is approx 24,000 miles. So, take that divided by 20 and that will tell you to bring some really comfortable shoes--it's gonna be a long walk timewise.

The radius of the earth is 6400kms. Therefore the circumference would be 2*22/7*6400. That would be 40228.6 kms
Now if speed equals distance travelled by time taken then we have t= 40228.6/32186.88 ( 20 miles = 32186.88 meters: SI system units)
Therefore t=1294833120.768 seconds
1 294 833 120.768 seconds = 359 675.867 hours
=14986.494458333333333333333333333 days
=41.05 years
Whew!! Got it now?

If there were land all the way, it would be 25000/20 = 1250 hours. But that's a fast walk, and you would have to do a fair amount of swimming.
