Question

an object moves 18m in the first 3s,22m in the next 3 s and 14m in the last 3 s. what is its average speed

Answer 1

We already know that average speed = Total distance/Total time taken

Total distance= 18m +22m+ 14m= 54m
Total time taken= 3s+ 3s+ 3s= 9s

So, average speed = 54/9 m/s
=6 m/s
