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

Answer:

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

Step-by-step explanation:

Let

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

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

we know that

$\frac{x}{y}=\frac{24}{20}=1.2$

$x=1.2y$ -----> 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

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

Answer 2

Answer:

the length of the boat on his sketch is 12 cm
