Question

a object travels 10m in 2s and next 10m in 4s. what is the average speed of the object​

Answer 1

Answer:

20/7 m/s  or 2.85 m/s

Explanation:

Total distance travelled by the object = 10 m + 10 m = 20 m

Total time taken by the object = 2 s + 5 s = 7 s

We know that,

Average speed = Total distance travelled / Total time taken

                         = 20/7 m/s  or 2.85 m/s
