we can make a relation and use cross multiplication
if Rita traveled 1,250 miles is 3 days how much days take to travel 1,875 miles
so
[tex]\begin{gathered} 1,250\longrightarrow3 \\ 1,875\longrightarrow x \end{gathered}[/tex]where x is the number of days to 1,875miles
to solve we multiply 1,875 by 3 (so the diagonal numbers ) and divide between 1,250
then
[tex]\begin{gathered} x=\frac{1,875\times3}{1,250} \\ \\ x=\frac{9}{2}=4\frac{1}{2} \end{gathered}[/tex]so she takes 4 and a half days
