Answer 2

Explanation:

Hey MATE.........

$as \: we \: know \: that \: \\ \\ t = \frac{d}{s} \\ \\ t1 = \frac{240}{80} \\ \\ \: \: \implies\: 3 |hr| \\ \\ \implies \: t2 = \frac{360}{90} \\ \\ \implies 4 |hr| \\ \\ total \: distance = 360 + 240 \\ \\ \implies600km \\ \\ total \: time = 4 + 3 = 7 \\ \\ average \: speed = \frac{total \:distance }{total \: time} \\ \\ \implies \frac{600}{7} \\ \\ \implies85.7(approx)km |hr|$

HOPE IT HELPS YOU
