We know that:
[tex] \large {\bold{{\binom{ d \: = \: 30}{t \: = \: 2}}}}[/tex]
[tex] \large \bold{Substitute \: \binom{d \: = \: 30}{t \: = \: 2} }[/tex]
[tex] \rm {d \: = \: v \: \times \: t}[/tex]
[tex] \rm{30 \: = \: 2v}[/tex]
[tex] \large \rm {\frac{30}{2} \: or \:30 \: ÷\:2} \\ \rm{Simplify}[/tex]
