If the scale used for a model is 1:48, then 2 1/2 centimeters on the model represents 120 meters. True or False??? Please help me! I've spent at least an hour already!!!

Question

jim_thompson5910 · Answer

2 and 1/2 cm = 2 + 1/2 cm

2 and 1/2 cm = 2 + 0.5 cm

2 and 1/2 cm = 2.5 cm

jim_thompson5910 · Answer

the ratio of scale:real is 1:48

ie, if you have 1 cm on the scale model, then you multiply it by 48 to get 48 cm

so 1 cm corresponds to 48 cm

It is certainly possible to replace the "cm" with "m" if you want the final real world units to be bigger

So...

1 cm : 48 m

2.5*1 cm : 2.5*48 m

2.5 cm : 120 m

So 2.5 cm on a scale model corresponds to 120 m on the actual object

unless they explicitly say  1 cm : 48 m   I would assume 1:48  means
1 cm represents  48 cm

that means  2.5 cm  represents 2.5*48  or 120 cm   or 1.2 meters
