Average speed of the trip = 52 km/hr

Further explanation  

Distance is the length traveled by an object within a certain of time .

Average speed = total distance/total amount of  time ,

Can be formulated :

[tex]\tt S(speed)=\dfrac{D}{T}[/tex]

Total distance travelled : 1560 km

Total time : 8 hr + 12 hr + 10 hr = 30 hr

[tex]\tt avg.speed=\dfrac{tot~D}{tot~T}\\\\avg.speed=\dfrac{1560}{30}\\\\avg.speed=52~km/hr[/tex]
