Average speed= Total distance/Total time
Total Time= 3hrs+5hrs=8hrs
we know,
speed= distance/time
so,
distance= speed×time
For first 3 hrs, the distance will be
⇒ 60×3
⇒180km
For the next 5 hours, The distance will be
⇒35×5
⇒ 175km
The total distance is,
180km+175km
⇒355km
Average speed= 355/8
⇒44.375km/h
