Question

The formula for calculating power is work divided by time (power = work ÷ time). What are two ways of stating the same relationship? work = power ÷ time, work = power × time, time = work ÷ power, time = work × power, power = work × time

Answer 1

Answer:

work = power × time,

time = work ÷ power

Explanation:

we can write the original relationship as:

$P=\frac{W}{t}$

where P is the power, W is the work, and t is the time.

First of all, we can rewrite the equation by isolating W, as follows:

$P=\frac{W}{t}\\P \cdot t = \frac{W}{t} \cdot t = W\\W=P\cdot t$

which corresponds to

work = power × time,

And then, we can re-write it as

$W=P \cdot t\\\frac{W}{P} = \frac{P\cdot t}{P}=t\\t = W \cdot P$

which corresponds to

time = work ÷ power

Answer 2

The answer is work= power × time !!
