Homework Statement
"Power is the rate at which work is performed.
Power is signified by W for watts.
Power is also the amount of energy transmitted in a unit of time (s).
Energy is measured in joules. Joules have the units of Newton∙meters.
A Newton is a unit of force. It is equal to the amount of force required to give a 1 kilogram mass and acceleration of one meter per second squared."
Using the aforementioned information, determine the units for power by completing a dimensional analysis.

The Attempt at a Solution
Ok so I know that the units for power are Joules/seconds.. How would you go about getting this by dimensional analysis at all?
So I've done
P = J/s
Power (P) = Work (W)/time (t)
P is in Watts (W)
Watts is J/s
Not sure at all what to do, this is worded so weirdly.. If anyone could help me see what exactly to do, that'd be appreciated.
