we know that
Amanda can jog [tex]18[/tex] miles in [tex]5[/tex] hours
so
by proportion
Find the number of miles that Amanda can jog in [tex]4[/tex] hours
[tex]\frac{18}{5} \frac{miles}{hours} =\frac{x}{4} \frac{miles}{hours} \\ \\5*x=18*4 \\ \\x=72/5 \\ \\ x=14.4\ miles[/tex]
therefore
the answer is
[tex]14.4\ miles[/tex]
