Question

A trimaran boat, with a top speed of 55 knots, won the tournament cup in 2010. Its top speed is 6 knots more than 3.5 times the top speed of the winner monohull in the 2007 tournament. Find the top speed of the monohull in the 2007 tournament

Answer 1

14 knots

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 m. Now, let's set up an equation:

`55 = 6 + (3.5 * m)`

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

`49 = 3.5 * m`

Dividing both sides by 3.5 we get:

`14 = m`

That means that the top speed of the monohull in the 2007 tournament was 14 knots
