0.024m/s

Explanation:

Firstly, we have to convert the 3.20cm/s to m/s which is done by dividing the 3.20 by 100. the answer gives 0.032m/s. Then using the formular v=c/n where v is the apparent speed, c = speed of object and n is the refractive index of medium. we can now solve using the above formular which is 0.032m/s/1.333 = 0.024m/s
