Her friend's height is 5 feet
Madeleine's height is given as:
Height = 6 ft
The height of her shadow is represented as:
Shadow = 108 inches
Her friend's shadow is 1.5 feet (i.e. 18 inches) shorter.
So, we have:
Friend's shadow =108 inches - 18 inches
Friend's shadow = 90 inches
So, we have he following equivalent ratio
[tex]6 : 108 = h : 90[/tex]
Express as fraction
[tex]\frac{6}{108} = \frac{h}{90}[/tex]
Multiply through by 90
[tex]5 = h[/tex]
Rewrite as:
[tex]h = 5[/tex]
Hence, her friend's height is 5 feet
