The most ancient examples of primitive lifejackets can be traced back to inflated bladders of animal skins or hollow, sealed gourds, for support when crossing deeper streams and rivers. The modern lifejacket is generally credited to one Captain Ward, a Royal National Lifeboat Institution inspector in the United Kingdom, who, in 1854, created a cork vest to be worn by lifeboat crews for both weather protection and buoyancy.

You and a pair of life preservers are floating down a swift river you wish to get to either of the life preservers for safety 1 is 3 meters upstream and 1 3 meters downstream which can you get to fast?
If each life preserver is 3 meters on either side, up and down, then you will reach either life preserver with the equal amount of time. As both you and the two life preservers are travelling downstream at equal speed. If you swim to the life preserver upstream you are effectively slowing yourself down and allowing the life preserver upstream to catch up to you. On the other hand, if you swim to the life preserver downstream you are effectively speeding yourself up to catch up to the life preserver downstream. As the frame of reference is the movement of the river, your distance to either life preserver is the same and hence can be reached with the equal amount of time. Answered by Ask4MyTutor

How does a life preserver help you float easier?
The density of a life preserver is what helps you float. The preserver has a much lower density then water so it's own density makes it float, but it is so thin (not dense) that it helps makes up for the fact that we are between 80 and 90% water.
