Answer:
The change in height of the glider is 3/20 mile
Step-by-step explanation:
we know that
To find out the change in height of the glider subtract 3/5 mile from 3/4 mile
[tex](\frac{3}{4}-\frac{3}{5})[/tex]
Find the LCM of denominators
[tex]LCM=(4)(5)=20[/tex]
[tex](\frac{3}{4}-\frac{3}{5})=\frac{5*3-4*3}{20}=\frac{3}{20}\ mi[/tex]
therefore
The change in height of the glider is 3/20 mile
