Speed

The distance covered by a moving object in a unit of time.

Calculating Speed

To calculate speed, divide the total distance traveled by the total time taken.

Distance per Second

The total distance covered by the satellite in 4 seconds is 84.4 km, and we need to find the distance covered in 1 second. Divide the total distance by the total time to find the distance covered in one second.

Total Distance Calculation

Once you know the distance traveled in one second, multiply it by the total number of seconds (6 seconds in this case) to find the total distance traveled.

Study Notes

Satellite Orbiting a Planet

A satellite orbiting a newly discovered planet travels 84.4 kilometers (km) in 4 seconds at a constant speed.
The satellite will orbit for 6 seconds in the next pass, covering the same distance each second.
The distance traveled each second is 84.4 km / 4 s = 21.1 km/s.
