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.
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..
s=d/ts= 100 / 12s= 8.33ms-1
A total of 30 seconds - assuming they run at a constant speed.

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.
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..

No. If you divide a distance by a speed, you get a time, not a speed. For example, (meters) / (meters/second) = (seconds).
s=d/ts= 100 / 12s= 8.33ms-1
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.
"Constant rate" implies there is no acceleration - acceleration is zero.

10 meters in 1.39 seconds equates to approximately 7.2 meters per second.
