What is the speed of a rock that travels 5000 meters in 5 seconds?

Answer 1

The speed is exactly (5000 meters)/(5 seconds), or 1000 meters per second.

In a somewhat more familiar unit, it's also 3,600 kilometers per hour, which is

really steppin' along! That's about 2,237 miles per hour, and about 3 times

the speed of sound.

Answer 2

5000 m / 5 secs

1000 m / 1 sec

1 km / 1 sec

or 1 km per sec.
