Answer:
Average speed= total distance /total time taken=
1000+ 500/ 45*60 m/s =
1500/2700 m/sec = 0.55 m/sec
Average velocity = total displacement /total time =
500/2700 m/sec
= 0.185 m/sec

Answer:
1)avg.speed=total dist / total time
Total distance=2+2=4km
Total time =time home to market +time market to home
=2/4+2/6
0.83
Avg speed =4/0.83=4.8kmperhour
2)avg vel=0 since total displacement is 0
3)in 30 min the boy travelled 2km =4kmperhour
In40 min he travelled 2+1=3km
Avg speed=3/1.5=2kmperhour
