Arock climber's elevation above sea level changed −82 1/2 feet in 2 1/4 minutes as she descended.
what was the climber's average change in elevation per minute?
enter your answer as a mixed number, in simplified form, in the box.
answer quickly , .

Step-by-step explanation:

The elevation changed in . To find the ratio of change of such elevation, we just have to divide these quantities. However, we need to transform each mixed number into a fraction, as follows

Then, we divide

Therefore, the ratio of change expressed as a mixed number is

2

step-by-2step explanation:

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
