Rory is staying in a cabin on a hill 300 feet above sea level. She walks down the hill to the water’s edge. The equation of her average change in elevation over time is e = 300 – 10t, where t is the time in minutes since she left the cabin, and e is her elevation with regard to sea level. Which values are viable points, and what are their values in the table relating t and e?

Answer and Step-by-step explanation:

As per the given situation we have following equation

e = 300 - 10t

The elevation and the time can not be in the minus

= t ≥ 0

and

e ≥ 0

As per the provided equation, beginning at the time which is

t = 0

while

elevation which represents e = 300

whereas at the top,

when elevation = 0

So time will be

t = 30 minutes

Therefore, The viable points will be

(0 , 30) and (300 , 0)
