A glider begins its flight 3/4 mile above the ground. After 30 minutes, it is 3/5 mile above the ground. Find the change in height of the glider?

Respuesta :

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
