a) 8:14
b) 6:8
yeah its telling me I'm short of words
Answer:
14 knots
Step-by-step explanation:
We know the speed (55 knots) is 6 more than 3.5 times the winner of the monohull in the 2007 tournament.
So let's set the variable for the speed of the monohull to <em>m</em>. Now, let's set up an equation:

We can solve this by first subtracting 6 from both sides to get:

Dividing both sides by 3.5 we get:

That means that the top speed of the monohull in the 2007 tournament was 14 knots
Add together your portions 1 + 3 + 5 = 9
divide 72 by 9 = 8
Each portion is multiplied by 8
1 x 8 = 8
3 x 8 = 24
5 x 8 = 40
Your portions are 8kg:24kg:40kg
Is this correct? Add 8 + 24 + 40. Do they equal 72? yes. Your portions are correct.
