Sup /sci/ducks.

I've been going over some Astronomy notes for a midterm, and I am confused with Kepler's second law of planetary motion. The Cosmic Perspective textbook says:
"As a planet moves around its orbit, it sweeps out equal areas at equal times."
Then, directly underneath it, it clarifies it: "Planets move at a greater distance at its perihelion than it does at its aphelion."

Doesn't this contradict the former statement? I understand the law, but I don't understand the former explanation. The fuck.

Can anyone clear this up for me?

tl;dr I'm retarded.

Second result on google. You really couldn't have done that yourself?
