Answer 1

Step-by-step explanation:

Wear swim goggles or dive mask to see more clearly.

Wear swim flippers (aka fins) to swim faster, cover more distance, with less effort. The flippers increase the surface area of a lifeguard's feet, so there's more area to push against the water. Newton's 3rd Law says the reaction force of the water on the flippers propels the swimmer forward.
