If a hiker starts at sea level and increases her elevation at a rate of 1 foot per minute what will her elevation be in 20 minutes

20ft

Step-by-step explanation:

Sea level is at 0 and the hiker hikes for 20 minutes at a rate of 1 foot. 20*1=20.

0+20=20

20 feet above sea level.

Explanation:

This can be solved by looking at the Rate of Change. It is given that for ONE minute that passes by, her elevation increases by ONE foot.

With this rate, after 20 minutes, the elevation can be shown as:

20 min * 1 foot = 20 feet.
