Maggie is rock climbing. after reaching the summit, she descends 1r feets in 2 1/3 minutes. if she continues at this rate,where will maggie be in relation to the summit after 8 minutes.

You can use proportional reasoning to answer this question.

Set up a ratio with how far she traveled in the first 2 1/3 mins.  Make is equal to x feet in 8 minutes.  Solve using cross products.

1r feet           x feet
2 1/3 min  =   8 mins

8r feet = 2 1/3 x
2 1/3       2 1/3

3 3/7r feet = x

In 8 minutes, Maggie descended 3 3/7r feet.

Its the 3rd one.
