$\huge\bold{\color{aqua}{Solution :-}}$

$\quad\bold{V_{s}=\frac{V_1t_1+V_2t_2+V_3t_3}{t_1+t_2+t_3}}$

$\Rightarrow\bold{V_{s}=\frac{2.24×\frac{1}{60}+3.6×\frac{1}{60}+5.18×\frac{1}{60}}{\frac{1}{60}+\frac{1}{60}+\frac{1}{60}}}$

$\Rightarrow\bold{V_{s}=\frac{\frac{1}{60}(2.24+3.6+5.18)}{\frac{1+1+1}{60}}}$

$\Rightarrow\bold{V_{s}=\frac{\frac{1}{60}(11.02)}{\frac{3}{60}}}$

$\Rightarrow\bold{V_{s}=\frac{60×11.02}{3×60}}$

$\Rightarrow\bold{V_{s}=\frac{\red{\cancel{\blue{60}}}×11.02}{3×\red{\cancel{\blue{60}}}}}$

$\Rightarrow\bold{V_{s}=\frac{11.02}{3}}$

$\Rightarrow\bold{\green{\boxed{\red{V_{s}}=\pink{3.67}}}}$
