[tex]33 \: \: \frac{mile}{h} = \frac{d(1)}{t} \\ [/tex]

[tex]33 \: \: \frac{mile}{h} = \frac{d(1)}{x} \\ [/tex]

[tex]d(1) = 33x \: \: miles[/tex]

_________________________________

[tex]93 \: \: \frac{mile}{h} = \frac{d(2)}{t} \\ [/tex]

[tex]93 \: \: \frac{mile}{h} = \frac{d(2)}{5 - x} \\ [/tex]

[tex]d(2) = 93 \times (5 - x) \: \: \: miles[/tex]

[tex]d(2) = 465 - 93x \: \: \:miles[/tex]

_________________________________

[tex]d(total) =d(x) = d(1) + d(2) \\ [/tex]

[tex]d(x) = 33x + 465 - 93x[/tex]

[tex]d(x) = - 60x + 465[/tex]

Done...
