And then the units are meters per second. And that is his average speed. And what we're going to see in a second is how average speed is different than instantaneous speed, how it's different than the speed he might be going at any given moment. And just to have a concept of how fast this is, let me get the calculator back. This is in meters per second. If you want to know how many meters he's going in an hour, well, there's 3,600 seconds in an hour. So he'll be able to go this many meters 3,600 times.
