A model of a ship is made to a scale of 1: 400. If the length of the model is 8 m, calculate the length of the ship.
320 metres
3200 metres
32 metres
16 metres
The scale factor is 1:400.∴k=400We have,Length of the ship =k× Length of the model=(400×8) metres=3200 metres
A model of a ship is made to a scale of 1:250. Find the length of the ship, if the length of the model is 1.6 m.
