How far is 30 km?

30 km is pretty far. It's about 18 miles, which is almost a marathon. That's a long way to walk or run, and most people wouldn't be able to do it without training. Even if you're in good shape, 30 km is still a distance that most people couldn't just go out and do without preparing for it. It would take a couple of hours to walk, and even longer to run.

Assuming you walk at a moderate pace of around 3 mph, it would take you 10 hours to walk 30 km. This is because there are around 24 km in 1 hour. Therefore, it would take you 240 minutes, or 4 hours, to walk 30 km.

Assuming you are running at a constant speed, it would take 216,000 seconds, or 360 minutes, or 6 hours to run 30 km. This is based on the equation d = vt, or distance = velocity x time, where d = 30 km, v = 10 km/hr, and t = 216,000 seconds.

An astronomical unit (abbreviated as AU, au, a.u., or ua) is a unit of length equal to about 150 million kilometers, or ~93 million miles. It is approximately the distance from the Sun to Earth. As such, it is used to measure distances within the Solar System. It is also a common unit used to express distances to nearby stars and extrasolar planets.

One astronomical unit is equal to about 4.85 million mi (8.32 light-seconds, or 2.06×1013 km). Therefore, 30 km in astronomical units is about 9.51×10-11 AU, or 9.14×10-12 light-years.

There are conflicting definitions of what a parsec actually is, but for the purposes of this essay, we will assume that a parsec is equal to 3.2616 light years. Therefore, 30 km in parsecs is equal to 3.2616 * 30,000 / 1000, or 97.848 light years.

30 km is equal to 30,000 m. In scientific notation, this is 3 x 104 m. Thus, 30 km is 3 x 104 m in scientific notation.
