<span>Taking this to a Physics formula of Time equals energy times efficiency over power equals (5670kJ)(0.25) over 800J/s equals 1770 s which gives the solution 30 minutes.
Therefore, it will take 30 minutes for a 68kg person to swim at a fast crawl in order to use all the energy available in a typical fast food meal of a burger, fries, and a drink. I estimated with a 25% efficiency for work capacity at swimming at a fast crawl in this equation.</span>

B
Step-by-step explanation: 6 21 9 45
49 × 17 + 49 × 3
49 × (17 + 3)
49 × 20
Answer:
<u>So, the way a ratio works is </u><u>"for every 1 of this, we have 4 of this"</u><u> for example. (the ratio I just described would be 1:4.) </u>
<u />
I believe I've seen this question before. If the ratio of dolls to teddy bears is 9:3 then for every 9 dolls you have 3 teddy bears.
So, since we have 240 dolls and a 9:3 ratio to teddy bears, all we have to do is take how many dolls we have (240) and divide it by 3 to see how many teddy bears we have.
So:
240 ÷ 3 = 80
If your ratio is 9:3, then 80 is your answer.
