Speed in physics is called velocity what you are looking for when you are talking about speed/velocity you are looking for an answer with the units being "distance/time" such as "miles/hour" in this case you are using the distance measurement of meters and the time unit of seconds therefore you want an answer in "meters/second." Ergo, you divide the unit of distance by time so it would be "45 meters/5 seconds" which would simplify to "9 meters/second" where the symbol "/" can be pronounce as "per" so it could be written "9 meters per second"
I hope you did just get the answer, but rather some of the thought process of the issue.
Just divide the distance by the time. (In this case, the speed in the answer will be in meters per second.)
Speed = distance/time => Speed = 20m / 5s => Speed = 4 m/s or 4 ms-1
Speed = (distance traveled) divided by (time to cover the distance) Speed = (50 meters) / (2 seconds) Speed = 50 meters per 2 seconds Speed = 25 meters per second
Acceleration = (change in speed)/(time for the change) = (15-5)/(6) = 10/6 = 12/3 meters per second2
Speed equals Distance over Time. Distance = 35 metres, Time = 5 seconds. 35/5 = 7 metres per second or 7ms-1
If an object moves 50 meters in 5 seconds, its average speed is 50/5 = 10 meters per second.
A rocket that travels 9000 meters in 12.12 seconds moves at 742.5742 meters/second which is approx 1660 mph
Just divide the distance by the time. (In this case, the speed in the answer will be in meters per second.)

Speed = distance/time => Speed = 20m / 5s => Speed = 4 m/s or 4 ms-1
Speed = (distance traveled) divided by (time to cover the distance) Speed = (50 meters) / (2 seconds) Speed = 50 meters per 2 seconds Speed = 25 meters per second
what is the speed of a rocket that travels 9000 meters in 12.12 seconds
Acceleration = (change in speed)/(time for the change) = (15-5)/(6) = 10/6 = 12/3 meters per second2
Use the formula: Speed = distance / time. If you divide meters / seconds, the speed will obviously be in meters/second.
395000 meters/9000 seconds is 43.889 meters/second
4 meters/2 seconds = 2 meters/second.
