Solution

The correct option is B
400 m

Let us suppose that the length of the model is denoted by M and length of the actual ship is denoted by A.

$\frac{M}{A} = \frac{1}{250}$

$\frac{1.6}{A} = \frac{1}{250}$

$A = 1.6 \times 250$

A = 400 m

The correct option is B 400 m Let us suppose that the length of the model is denoted by M and length of the actual ship is denoted by A. MA=1250 1.6A=1250 A=1.6×250 A = 400 m

The correct option is B
400 m

Let us suppose that the length of the model is denoted by M and length of the actual ship is denoted by A.

$\frac{M}{A} = \frac{1}{250}$

$\frac{1.6}{A} = \frac{1}{250}$

$A = 1.6 \times 250$

A = 400 m
