Hyy Dude
Distance1 = 20 m
Time1 = 4 s
Distance2 = 20 m
Time 2 = 10 s
Total Distance(D) = 20m + 20m = 40m
Total Time(T) = 4s + 10s = 14s
Average Speed = Total Distance(D) / Total
Time(T) = D/T = 40/14
= 2.857 m/s
May this helps you
Plz marked in brainlest answer
Answer:
9 m/s
Explanation: as we know that avg. speed = total distance/total time.
Therefore, (20+16/2+2)m/sec
=(36/4)m/sec
=9m/sec
