If astronauts travel to the Moon and back to Earth again in 144 hours how many kilometers per hour do they travel?

Around 5339 km/hour is the result for the "average speed" but the actual top speed would be much higher, and the lowest speed much lower. In the 148-hour trip by Apollo 8 in 1968, the spacecraft spent 2 hours in Earth orbit before traveling to the Moon, and 67 hours getting there. They spent 20 hours making 10 orbits of the Moon, at an average speed of about 6000 km/hr. On the last leg of their return to Earth, they traveled 400,000 km in 55 hours and reached a maximum speed of 40,000 km/hr.
The "average" distance to the Moon is 384,400 km, so the round trip is a minimum of 768, 800 km.
The actual surface to surface distance is about 8100 km less, since the distance is measured from the center of the Earth to the center of the Moon, but you would probably have to orbit anyway.
768800 km / 144 hours = 5338.88 km/hr

An object travels 8 m in the 1st second of travel 8m again during the 2nd second of travel and 8m again during the 3rd second its acceleration in meters per second per second is?
Speed is constant. Acceleration is zero.
An object travels 8 m in the 1st second of travel 8 m again during the 2nd second of travel and 8 m again during the 3rd second Its acceleration in meters per second per second is?
Zero. It is not getting any faster or slower
A car traveled 1508 miles at 58 miles an hour how many miles did it travel?
Look at the question again; the answer is right there.
An object travels 8 m in the 1st second of travel 8 m again during the 2nd second of travel and 8 m again during the 3rd second Its acceleration is therefore?
Acceleration is zero velocity is constant at 8m every second acceleration is the gradient of velocity and the gadient of a constant = 0
A car slows to a stop in 5 seconds if it was going 80 kilometers an hour what was its acceleration?
You can't figure "acceleration" from this information. Maybe you meant "Deceleration"? Ask again.

What do most astronauts do with their sleeping bags?
Ummm well you know this is only a guess but even though their astronauts......wouldnt they sleep in their sleeping bags? but then again the only thing i know about astronauts is that they fly to the moon
Why do astronauts feel dizzy when they enter the earth's atmosphere from spending a long time in space?
They begin feeling gravity again which is now pulling all their blood and it changes their blood pressure and the fluid in the ear drums.
What is the distance between Jupiter and Earth in astronomical units?
.73 AU?But the distance from Mercury to the Earth varies greatly as both planets orbit the Sun. At its closest approach, Mercury is about 77 million kilometers (48 million miles) from Earth*. At its farthest, about 222 million kilometers (138 million miles).
How does the space shuttle move in space?
Most of the movement, the orbiting of the shuttle around Earth, comes from the launch which gets the shuttle up to over 17,000 miles per hour. While in orbit, astronauts use the the shuttle's reaction control system to make adjustments to the shuttles orbit. The main engines are used again at the end of the mission to slow the shuttle down allowing the Earth's gravity to the rest of the work to bring the shuttle and astronauts back to the ground.
What fraction of the world's surface is covered by Canada?
Canada has a total area (land and territorial waters) of slightly less than 10 million square kilometers. The total area of the surface of the earth (again, land and water) is about 510 million square kilometers, so Canada is a bit less than 2% of the total area of the earth. By land area alone, Canada is about 9 million square kilometers out of 149 million square kilometers, or about 6% of the total land area.

How do astronauts return to the earth. How do they propel their space shuttle back into the earth's atmosphere?
The thing that keeps objects in orbit around the Earth is their speed. It is a balancing act between the speed of the object trying to throw it out into space and gravity trying to pull it back toward Earth. If the object slows down gravity wins and it will fall back to Earth. So, to reenter they simply slow down. I wasn't sure I understood your question so if this was not what you were asking, ask again
You are standing on a point on earth called point A you walk north 10km east 10km south 10km now you are at point A again you are not at the south pole where are you?
You are approximately 5 kilometers away from the south pole?
How many kilometers the earth makes round the sun per hour day month year?
The Earth goes around the Sun at a speed of about 30 km/second. You can multiply that by 60 to convert to km/minute, again by 60 to convert to km/hour, etc.
Why did Mount Pinatubo become active again?
It became active again because a magnitude 7.8 earthquake, shook the Earth 60 miles away (100 kilometers), NorthEast. This earthquake also shook and squeezed the Earth's crust underneath Mount Pinatubo. The earthquake also caused a landslide on Mount Pinatubo; giving the volcano no support to stay underground.
