Answer:
[tex]If \: d \: represents \: the \: distance \: Moby \: travels, \: one \: way \: to \: write \: a \: proportion \: for \: this \: situation \: is \: \\ \frac{240}{4} = \frac{d}{10} [/tex]
[tex]Using \: cross \: multiplication \: gives \: us \: a \: new \: equation: \\ 2400 = 4d[/tex]
[tex]The \: final \: step \: is \: to \: divide \: by \: 4, \: which \: tells \: us \: that \: Moby \: can \: travel \: 600 \: miles \: in \: 10 \: hours[/tex]
Explanation:
Solve.
[tex] \frac{240}{4} = \frac{d}{10} \\ \\ \frac{4d}{4} = \frac{2400}{4} \\ \\ d = 600 [/tex]
