Figure This!

Quick Answer:

The glider with the glide ratio of 2/7 will fly farther.


Complete Solution:

There are several ways to approach this challenge.

One involves comparing how far the gliders descend after flying the same horizontal distance. To do this, write both ratios as fractions and find a common base (or denominator) for each one. For example, you could change both fractions to sevenths.

For A: Since   we have:

For B: 

One glider (A) descends 2.1 feet for every 7 feet of horizontal travel, while the other (B) falls only 2 feet over the same horizontal distance. The glider that falls more over the same horizontal distance will hit the ground. Therefore, glider B will fly farther.
