900 meters/30 seconds = 30 meters/second
9.804 meters per second.
A rocket that travels 9000 meters in 12.12 seconds moves at 742.5742 meters/second which is approx 1660 mph
The unit rate is how far something moves in ONE second. So in this case you divide by 28 (the number of seconds). 12/28=0.4285714285714286 meters a second.

50 meters in 10 seconds is faster. you go 5 meters per second in 50 meters per second, and you go 6 meters a second in 5 seconds..
That's easy, if the car is initially traveling at 25 meters per second and gradually accelerates 3 meters per second for 6 seconds then the car is traveling at 43 meters per second.
It's a bad question because 5 meters per second per secondis not"a constant speed"it is a rate of acceleration.5 x 5 = 25 meters traveled.

s=d/ts= 100 / 12s= 8.33ms-1
No. If you divide a distance by a speed, you get a time, not a speed. For example, (meters) / (meters/second) = (seconds).
"Constant rate" implies there is no acceleration - acceleration is zero.
There is no "unit for constant speed".The SI unit for speed (just "speed") is meters per second. Constant speed means there is no acceleration; the unit for acceleration is meters per second squared.
A total of 30 seconds - assuming they run at a constant speed.

meters per second is a speed measurement and seconds is a time so the amount of meters per second depend on both meters and seconds not just one
