Amodel ship is built to a scale of 1 cm: 4 m. the length of the model is 40 cm. what is the length of the actual ship?
a: 160 b: 50 c: 40 d: 15

Option A is correct that is length of actual ship is 160 m.

Step-by-step explanation:

Given: Scale for model ship is 1 cm model ship : 4 m Actual Ship.

To find: length of the actual ship.

length of actual ship when model ship is 1 cm = 4 m

So, Length of actual ship when model ship is 40 cm  = 4 × 40

                                                                                        = 160 m

Therefore, Option A is correct that is length of actual ship is 160 m.
