In the sea, since the shoes are heavier they will travel faster in a lower point.
Step-by-step explanation:
The situation that has been put up in the question are the shoes and the ducks which are made of rubber. When the weight of the two is compared, it is obvious that the shoes are heavier than the ducks which are made out of rubber.
As a result of this, in the sea, the shoes will go to a lower point where as the ducks will remain at a higher level only. Being at a lower level. the shoes will travel faster compared to the ducks.
