<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>
2+3=5
25/5=5
5x2=10 3x5=15
so the answer is:
£10:£15

Answer:
2100
Step-by-step explanation:
In how many ways can a group of 10 people be divided into three groups consisting of 2,3, and 5 people?
First, you need to choose 4 people to fill the first group.
The number of ways is (104) which equals to 210.
Then, pick 3 more people out of the remaining 6 to be in the second group. And then, pick 3 more out of the remaining 3.
However, we need to divide it by 2, since we don’t really care on the order of selection of group.
(63)(33)/2=10
So, there are 210 x 10 = 2100 ways
