Answer:
A motor running at 75 revolutions per second.
Step-by-step explanation:
Given statement: A motor running at 4500 RPM, revolutions per minute.
⇒ In one minute , a motor running at 4500 revolutions.
Use conversion:
We have to calculate how many revolutions per second.
in 60 sec , a motor running at 4500 revolutions
then,
in 1 sec , a motor running at 
revolutions.
Therefore, a motor running at 75 RPS, revolution per second.
From the answer, let's assume that you can only use each number once.
So there are four slots.
_ _ _ _
For the first slot, you have a possibility of 9 numbers.
9 _ _ _
Now for the second slot, you have the possibility of 8 numbers.
9 8 _ _
Now for the third slot, you have the possibility of 7 numbers.
9 8 7 _
Now for the last slot, you have the possibility of 6 numbers.
9 8 7 6
Now multiply these numbers together and you should get 3,024.
