At t = 2
x1 = 18*2 + 5*2^2
x1 = 56 m
At t = 3
x2 = 18*3 + 5*3^2
x2 = 99 m
Average velocity = Total displacement / Total time
= (x2 - x1) / (t2 - t1)
= (99 - 56) / (3 - 2)
= 43 m/s
Average velocity is 43 m/s
x1 = 18*2 + 5*2^2

At t = 3
x2 = 18*3 + 5*3^2

Average velocity = Total displacement / Total time
= (x2 - x1) / (t2 - t1)
= (99 - 56) / (3 - 2)
= 43 m/s
Average velocity is 43 m/s
