Answer:
Sam walked 1.2 miles
Step-by-step explanation:
We are given
Sally walked 12 miles
so,
[tex]SL=12miles[/tex]
Let's assume distance traveled by Sam is SM
Her brother Sam walked 1/10 as much as Sally
so,
[tex]SM=\frac{1}{10}SL[/tex]
now, we can plug value
[tex]SM=\frac{1}{10}\times 12[/tex]
[tex]SM=1.2[/tex]
So,
Sam walked 1.2 miles
