How long does it take to travel from one side of earth to the other?

Answer 1

That naturally depends on how fast you run. And for at least half of the trip, how fast you swim.

Last summer, Usain Bolt ran the 100 meters in world-record time of 9.58 seconds. Since

you are not as fast as Bolt, and also since you'll have to keep doing it many times, let's

assume . . .

--> it takes you a full 10 seconds to run 100 meters, and

--> you can swim just as fast as you run, so the Pacific Ocean doesn't slow you down a bit, and

--> you do your run/swim around the equator.

The earth's equatorial circumference is (12,756 pi) km = 40,074 km .

At 10 seconds per 100 meters, it will take you 46days 9hours 10minutes16seconds ...

at almost the speed of Usain Bolt, never stopping to eat sleep or whatever, in order to

get back exactly to where you started.

Personally, I would not do it. As the old story goes: "On me, you shouldn't depend!"

Answer 2

It depends on your method of transport. Walking would take several months, use of commercial aircraft may take 30-40 hours, while someone in the international space station would take about an hour and a half.

Answer 3

There are several factors you need to consider. Two important questions are: 1) How complete do you want your coverage? and 2) How fast will you travel? Let's say you want to be within sight of every bit of dry land on the planet. According to Wikipedia, the surface area of the land on Earth is ~150,000,000 square km. If you are roughly 6 feet tall, your visible horizon is about 5 km, which means you can see, on average about 150 square kilometers around you. Now if your walking, a comfortable pace is ~5 km/hr. So if you consider there are ~1,000,000 "horizon circles" of land on earth, and it takes about 2 hours to walk from the center of one to the other, then you would be walking for about 2,000,000 hours to see the whole earth. That's 685 years. So now you need to start talking about moving faster (cars, buses, trains, planes), and skipping some parts.

Answer 4

Probably depends on how close together they stand, do you suppose ?

This question sounded interesting, so I spent a few minutes with it, and I calculated like this: How close together would people have to stand in order for the earth's population to wrap around the equator exactly one time ?

Data:

1 mile = 5,280 feet

World population: Let's say six billion.

Earth's equatorial diameter: 7,926 miles

Equatorial circumference = [ 7,926 pi ] miles = [ 7,926 x 5,280 pi ] feet

Space for each person = (circumference) divided by (population) = (7,926 x 5,280 pi) / 6,000,000,000

= 0.0219 foot = about 1/4 inch per person

Answer 5

That depends a lot on the speed. Use the formula distance = speed x time; solving for time: time = distance / speed. The circumference of Earth is 40,000 km. For a ray of light, it takes less than 1/7 second.

Answer 6

The earth itself spins roughly once every 24 hours ... the period of time we call a "day".

At the same time, it travels a long path around the sun once every 365.24 days ... the

period of time we call a "year".

For your added interest, the entire solar system orbits the centre of the Milky Way Galaxy, which itself is travelling outwards in space. So the Earth travels in four different ways all at the same time - clever, huh?

Answer 7

That would obviously depend on the speed. Pick a suitable speed, then divide the Earth's circumference (40,000 km) by that speed. If the speed is in kilometers per hour, the answer will be in hours. This assumes you go in a straight line - if (for example) you go by boat, you have to avoid continents, and have to go a longer route.

Answer 8

It is said that if you wish to travel across the entire world, it would take over a year and five months. Unlike in the book and movie "Across the world in eighty days" Which is clinicly proven isnt possible at any circumstances.

Answer 9

Answer 10

The Earth doesn't really travel around the Earth. It rotates on it's axis, and that take 24 hours.
