An object travels `16 m` in `4 s` and then another `16 m` in `2 s`. What is the average speed of the object?

Options

A. 5.33 m/s
B. 53.3 m/s
C. 4.20 m/s
D. 4.30 m/s

Answer

5.33 m/s

Explanation

Total distance travelled by the object =
16 m + 16 m = 32 m
Total time taken = 4 s + 2 s = 6 s
`"Average speed" = ("Total distance travelled")/("total time taken")`
`= (32 m)/( 6 s) = 5.33 m s^(–1)`
Therefore, the average speed of the object is `5.33 m s^(–1)`.
