Question

an object moves 20m in the first s 45, 24m in the next 4s and 16m in the last 4s then what is it's average speed​

Answer 1

Answer:

Explanation:

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

Answer 2

20+24+16
