Answer 2

Explanation:

$\huge \red{ \boxed{ \blue{ \boxed{ \green {average \: speed = }}}}} \\ \huge \red{ \boxed{ \blue{ \boxed{ \green { \frac{total \: distance}{total \: time} }}}}}$

$total \: distance\boldsymbol{ \longrightarrow}80×4=320km + 60×6=360km = 680km \\ total \: time\boldsymbol{ \longrightarrow}6 + 4 = 10hrs$

$\huge \red{ \boxed{ \blue{ \boxed{ \green {according \: to \: question}}}}}$

$\huge \red{ \boxed{ \blue{ \boxed{ \green { \frac{680km}{10hrs} }}}}} = \huge \red{ \boxed{ \blue{ \boxed{ \green {68km |hrs}}}}}$
