Hi Nancy. Welcome to pprune.
why we land in to the wind? would it not be quicker to land with the wind to arrive earlier?
While coming in to land, your aircraft's speed is very slow. At slow speeds, a headwind will allow you to land safely without dropping(stalling). Sometimes, quicker is not better (or safer). Anyway, you have headwind only when you are on finals, which is a very small portion of your flight.
This was a simple explanation. If you want to learn more, read up about Lift in the BAK book or Aerodynamics book. You can also ask again here.
Focus on one flight at a time and have fun!
