150m

Explanation:

work is force * distance

150000 = 1000*d

d=150

Hey there! If you remember, the amount of work is written in joules (J). so when we say the elevator did 150,000 J of work, that is what its talking about. Then, it tells you that this elevator is exerting a force of 1000 N to take people to the top floor. Well, N stands for Newtons, and this just measures how much energy is being put into something.

So now that we know what everything means, lets solve the equation!

Hopefully, you've picked up what the equation to find work, or joules, which is W=Fd. Work=Force x distance. In math, when you switch around a multiplication equation like this, it is usually the opposite, division. So, we want to find the distance the elevator traveled, so that is going to be our product.

d=

Good? Ok. The next part is just putting together what we already worked out, which is going to be 150,000 J divided by 1000N.

d= 150,000J / 1000N

Then, all you have to do is solve! When you plug it into a calculator, which is what I did, then you do not have to put in the coefficients,  so just the numbers. You will get 150.

Distance is measured in meters, so you will label your final answer in meters. 150m. I really hope this helps you, Have a great day!
