Answer 1

$\huge \sf {\orange {\underline {\pink{\underline{Answer :-}}}}}$

$\sf{From ~ A~ to~ B}$

$\sf{Time~ from A ~to~ B }$

$\sf\mapsto{=2 ~mins}$

$\sf\mapsto{= 2 × 60~ sec}$

$\sf\mapsto{= 120 ~sec}$

$\sf\green{Average~ speed}$

$\longrightarrow\dfrac{total \: distnce}{total \: interval}$

$\sf\longrightarrow \dfrac{200}{120 }$

$\sf\longrightarrow {1.6m/ s}$
