The glider with
the glide ratio of 2/7 will fly farther.
There are several ways to approach this
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
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.
