Letthetotaldistance(Dt)travelledbe2xkm.Letthetotaldistance(Dt)travelledbe2xkm.

Halfofthetotaldistance=2x2=xkmHalfofthetotaldistance=2x2=xkm

Timetakentotravelfirsthalfofthedistance,T1=x40hoursTimetakentotravelfirsthalfofthedistance,T1=x40hours

Timetakentotravelsecondhalfofthedistance,T2=x60hoursTimetakentotravelsecondhalfofthedistance,T2=x60hours

Totaltimetaken,Tt=x40+x60Totaltimetaken,Tt=x40+x60

⟹Tt=3x+2x120⟹Tt=3x+2x120

⟹Tt=5x120⟹Tt=5x120

⟹Tt=x24⟹Tt=x24

Averagespeed,Va=Dt÷TtAveragespeed,Va=Dt÷Tt

⟹Va=2x÷x24⟹Va=2x÷x24

⟹Va=2x×24x⟹Va=2x×24x

⟹Va=2×24⟹Va=2×24

⟹Va=48km/hr⟹Va=48km/hr

∴Averagespeedofthecaris48km/hr
