# In a model of a ship, the mast is 9 cm high, while the mast of the actual ship is 15 m high. Ifthe length of the ship is 35 metres, how long is the model ship?

The length and the height of ship and model should be proportional.

Height of mast of actual ship = 15 m

Height of model ship = 9 m

Length of ship = 35 m

Length of model = x

So,

15/35 = 9/x

Cross multiplying, we get,

x = (9 × 35)/15

x = 21 m

Length of model of the ship is 21 m.
