A boy runs 400 meters in 80 seconds.
What is his average speed?

To find the average speed, you simply divide the total distance by the total time. In this case, the boy ran 400 meters in 80 seconds, so his average speed is 400 meters divided by 80 seconds, which equals 5 meters per second. That’s like cruising at a nice pace—not too fast, but certainly no slouch!

Want to visualize what 5 meters per second looks like? Imagine running alongside a friend who’s casually jogging in the park. If you keep up that speed, you’d cover quite a distance without feeling overly exhausted. It’s an easily manageable pace for recreational runners!
