An object travels 16 m in 4 s and then another 16 m in 2 s. What is the average speed of the object?
Answer & explanation
Correct answer: option 2
Total distance travelled by the object = 16 m + 16 m = 32 m
Total time taken = 4 s + 2 s = 6 s
Average speed = \(\frac{\text{Total distance travelled}}{\text{Total time taken}}\) = \(\frac{32}{6}\) = 5.33 metres per second
