Answer:
3.33 m/s
Explanation:
Given :
- Distance travelled by the object in the first 4 seconds = 10 metres
- Distance travelled by the object in the next 5 seconds = 20 metres
To find :
- Average speed of the object
Average speed = total distance / total time
Total distance = 10m+20m
Total distance = 30 metres
Total time = 4 seconds + 5 seconds
Total time = 9 seconds
Average speed = 30/9
Average speed = 3.33 m/s
The average speed of the object is equal to 3.33 m/s

Answer:
Average speed = 3.33 m/s.
Explanation:
Distance₁ = 10 m Time₁ = 4 s
Distance₂ = 20 m Time₂ = 5 s
Average speed = Total distance / Total time
Total distance = (10 + 20) = 30 m.
Total time = 4 + 5 = 9 s.
∴Average speed = 30 / 9
Average speed = 3.33 m /s.
