Question

in a ship the mast is 9cm high, while the mast of the actual ship is 15cm high. If the length of the ship is 35 metres how long is the model ship.

Answer 1

Answer :

Let, the length of model of ship be x

Length of actual ship ( in m ) 15 35
Length of model ship ( in cm ) 9 x

Here length of mast and actual length of ship are in direct proportion.

Since, 15/9 = 35/x

=> x × 15 = 35 × 9

=> x = 35×9/15

=> x = 315/15

=> x = 105/5

=> x = 21 cm

Hence, the length of model of ship is 21 cm
