Answer:
B and C
Explanation:
The formula:
P = W / t (where P is power; W is work done; t is time)
Can be written in different ways, depending on what value you are trying to find. For example, if you have power, and time, but you want to calculate work, the formula can be rearranged to look like this:
W = P x t
It can also be rearranged to calculate for time:
t = W / P
Hence, the formula has three arrangements to calculate different values.
P = W / t ; W = P x t ; t = W / P
Comparing these formulas to the options given, it can be seen that options B and C are correct.
