Average speed of the trip = 52 km/hr
<h3>Further explanation </h3>
Distance is the length traveled by an object within a certain of time .
Average speed = total distance/total amount of time ,
Can be formulated :

Total distance travelled : 1560 km
Total time : 8 hr + 12 hr + 10 hr = 30 hr

The answer would be C. Hope this helps
A molecule with two strong bond dipoles can have no molecular dipole if the bond dipoles cancel each other out by pointing in exactly opposite directions. For example, in carbon dioxide (a linear molecule), the carbon-oxygen bonds have a <span>large dipole moment. However, because one dipole points to the left and the other to the right the dipole is cancelled.</span>
Legumes are much easier to grow than other plants, and are more adaptable.
Well all I know that animals take in oxygen and take out carbon dioxide and plants take in carbon dioxide and take out oxygen
