Question

Justin made a scale drawing of a sailboat he saw at the harbor. The length of the actual boat is 24 feet, and the mast is 20 feet high. In justin's sketch, the boat is 2 centimeters longer than the mast. What is the length of the boat on his sketch?

Answer 1

the length of the boat on his sketch is 12 cm

Explanation:

Answer 2

The length of the boat on his sketch is
`12\ cm`

Explanation:

Let

x------> the length of the boat on his sketch

y-----> the high of the mast on his sketch

we know that

`(x)/(y)=(24)/(20)=1.2`

`x=1.2y` -----> equation A

`x=2+y` ----> equation B

equate equation A and equation B

`1.2y=2+y`

`1.2y-y=2`

`y=10\ cm`

Find the value of x

`x=2+y` ------>
`x=2+10=12\ cm`
