On a scale drawing of a submarine, each 0.5 cm represents 3 m on the actual submarine. What length on the submarine is represented by 3 cm on the drawing?

Respuesta :

Answer:

The length of the actual submarine is 18 m.

Step-by-step explanation:

Here, the conversion ratio is

0.5 cm represents 3 m on actual submarine.

also, 3 m  = 3 x 100 cm  = 300 cm

or, the ratio of Drawing : Actual   =  0.5 : 300

Now, Here drawing = 3 cm

let the actual length of the submarine = k cm

By the RATIO of PROPORTIONALITY:

[tex]\frac{0.5}{300}  = \frac{3}{k}   \implies k = \frac{3 \times 300}{0.5}[/tex]

or, k = 1800 cm  = 18 m

Hence, the length of the actual submarine is 18 m.
