Question

an object travels 10 m in 2 seconds and then another 10 m in 1 second what is the average speed of the object?

Answer 1

Solution: Sum up the both distance
          i.e, 10m+10m=20m
                Sum up the time
          i.e, 2s+1s=3s

Now,    Avg. Speed=Distance/Time
            Avg. Speed=20/3=6.67m/s
