average speed =total distance covered /total time taken
time taken to covered 224 km at 70km/h =224/70 =3.2 hours
hence,
average speed =570/(3.2 +2)
=570/5.2 km/h
=109.61 km/h
time taken to covered 224 km at 70km/h =224/70 =3.2 hours
hence,
average speed =570/(3.2 +2)
=570/5.2 km/h
=109.61 km/h

Total distance =>570km
distance covered with speed 70km/hr= 224 km
Remaining distance=346 km
Total time taken to cover this distance= 2hrs
Speed= 346/2=173 km/hr
time for first journey= 224/70=3.2 hrs
time for second journey= 2 hrs
Average speed= total distance/ time taken= 570/(3.2+2)= 570/5.2=
109.6 km/hrs
Hope u understand
