Answer:

[tex]4.5 \: miles[/tex]

Step-by-step explanation:

[tex]rate = 18 \div 3[/tex]

[tex]rate = 6 \: miles \: per \: hour[/tex]

[tex]formula \: again = rate \: distance \div time \: [/tex]

[tex]6 = d \div 3 \div 4[/tex]

[tex]6 = 4d \div 3[/tex]

[tex]cross \: multiply[/tex]

[tex]18 = 4d[/tex]

[tex]d = 18 \div 4[/tex]

[tex]d = 4.5 \: miles[/tex]
