*Please Help!* (There are more than two answers!)

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

Answer 1

The answers are b and c

Answer 2

Answer: B. work = power × time

C. time = work ÷ power

Explanation:

Given : The formula for calculating power is work divided by time .

i.e.
`\text{power}=\frac{\text{work}}{\text{time}}`

When we multiply time both sides , we get

`\text{power}*\text{time}=\frac{\text{work}}{\text{time}}*\text{time}`

`\text{power}*\text{time}=\text{work}`

i.e.
`\text{work}=\text{power}*\text{time}`

When we divide both sides by Power , we get

`\frac{\text{work}}{\text{power}}=\text{time}`

i.e.
`\text{time}=\text{work}/\text{power}`

Hence, the two ways of stating the same relationship :

B. work = power × time

C. time = work ÷ power
