Answer:
average speed = total distance travelled / total time
Total distance travelled
= 30km/h * 0.5 h + 25km/h * 1 2/3 h
+ 40km/h *2 h
= 136.667 km
Total time = 0.5+1 2/3 + 2
= 4.1667 h
Average speed = 136.667/4.1667
= 32.8 km/h...hope helps plszz mark as the brainlist now also inbox me and follow me

Answer:
As we know that
average speed = total distance covered / total time taken
here, total speed is 30+25km/hr = 55 * 5/18 m/s
total time = 90 mins
so,average time = 15.27 / 90
=0.696
