Answer:
avrage speed = total distance / total time taken
=6km/h+4km/h/2h+3h
=10km/h/5h
average speed=2km/h
hope this helps
Answer:
Average speed is 4.8 km/hr and total distance moved is 24 km.
Explanation:
Given in first 2 hr the speed is 6km/hr and in next 3hr the speed is 4 km/hr.
To find average speed we need to find total distance moved because average speed is total distance moved in given time.
total distance moved, can be calculated using speed = distance/time so distance in first 2hr = speed × time= 6× 2= 12km
distance in next 3 hr= 4× 3= 12 km
total distance= distance in 2hr + distance in next 3hr= 12+12 = 24 km
now total time is 2+3= 5hr
now average speed= total distance moved/ total time
average speed= 24/5= 4.8 km/hr.
This is the required answer.
