Most of Jupiter's moons are less than 5 km across.

Of Jupiter's moons discovered so far, 55 of them are less than 5 km in diameter, or about 15.7 km in circumference. Assuming 15 minutes per km, and of course ignoring the effects of gravity (and the fact that there wouldn't be any air) a person could walk around one of these moons in about 235.5 minutes— just under 4 hours.
