Food vacuoles are formed by the fusion of phagosomes and pinosomes to lysosomes. Protozoans like Amoeba take their food by phagocytosis or pinocytosis. In phagocytosis, food particles are trapped by surrounding pseudopodia and they engulf it inside the cell forming a vesicle called phagosomes.

Starting from rest it means initial position will be zero convert 2 minutes into seconds to find speed we can use the equation v=u+at v will be our speed to find distance we can use the equation S(distance)=ut+1/2atsquare. So thats how you can find solution
