$\LARGE\gray{\boxed{\sf\blue{ t = 0s }}}$

⠀

➡ $\large\blue{\sf p = 4 + 3 \cdot (0) }$

$\large\blue{\sf = 4 + 0 }$

$\large\blue{\sf = 4~[m] }$

⠀

$\huge\green{\boxed{\rm~~~\red{ A)}~\gray{p}~\pink{=}~\blue{ 4~[m] }~~~}}$ ✅

Ⓑ$\bf\large\red{\underline{\qquad\qquad\qquad\qquad\qquad\qquad\qquad\quad}}$✍

⠀

$\LARGE\gray{\boxed{\sf\blue{ t = 1s }}}$

⠀

➡ $\large\blue{\sf p = 4 + 3 \cdot (1) }$

$\large\blue{\sf = 4 + 3 }$

$\large\blue{\sf = 7~[m] }$

⠀

$\huge\green{\boxed{\rm~~~\red{ B)}~\gray{p}~\pink{=}~\blue{ 7~[m] }~~~}}$ ✅

⠀

$\LARGE\gray{\boxed{\sf\blue{ t = 2s }}}$

⠀

➡ $\large\blue{\sf p = 4 + 3 \cdot (2) }$

$\large\blue{\sf = 4 + 6 }$

$\large\blue{\sf = 10~[m] }$

⠀

$\huge\green{\boxed{\rm~~~\red{ C)}~\gray{p}~\pink{=}~\blue{ 10~[m] }~~~}}$ ✅

⠀

$\LARGE\gray{\boxed{\sf\blue{ t = 3s }}}$

⠀

➡ $\large\blue{\sf p = 4 + 3 \cdot (3) }$

$\large\blue{\sf = 4 + 9 }$

$\large\blue{\sf = 13~[m] }$
