Answer:
660 mm
Step-by-step explanation:
we know that
The scale factor is [tex]\frac{1}{15}[/tex]
That means
1 unit in the model represent 15 units in the actual
or
1 m in the model represent 15 m in the actual
To find out the height of the model rocket, divide the height of the actual rocket by 15
so
[tex]9.9\ m=\frac{9.9}{15}= 0.66\ m[/tex]
Convert m to mm
Remember that
[tex]1\ m=1,000\ mm[/tex]
To convert meters to millimeters, multiply by 1,000
so
[tex]0.66\ m=0.66(1,000)=660\ mm[/tex]
