Real-Life Math

The world of hang-gliding is full of math. It involves both simple and complicated problems.

"You're always solving equations, even if you don't realize it. There's a ton of math that goes into it," says hang-gliding instructor Fred Burns.

Instructor Bodhi Kroll offers this simple example. "We use wind speed to anticipate how soon we're going to lift off the ground."

He says if there's no wind present, they have to run approximately 20 miles an hour down a steep slope.

"If the wind is coming up the slope at 15 miles per hour, then you'll have to get going at only 5 or 6 miles an hour," says Kroll.

But if the wind is blowing behind you at 15 miles per hour, you would have to run an unbelievable 35 miles per hour (adding 20 mph to the wind speed) to lift off! That's why they suspend flights whenever the wind is blowing from behind.

Consider these problems:

  1. The wind is blowing up the slope at 10 miles per hour. Approximately how fast will you have to run down the slope to achieve liftoff?
  2. The wind is blowing from behind at 10 miles per hour. How fast would you have to run to achieve liftoff?
