How fast other galaxies are moving away from us all depends on which galaxy, as they’re speeding away at different rates.
On top of that, everything that’s speeding away from the Milky Way is accelerating. Here’s a sampling on either end: One of the slower galaxies is speeding away at about 5,040,000 mph. That’s like going from one side of the United
States to the opposite side in about 2 seconds, give or take a little. One of the farther and faster galaxies is going so fast, it would take it about a second to go all the way around the world. It’s being clocked at about 93,600,000 mph.
The general rule is that the farther the galaxy is from the Milky Way, the faster it’s going.
