Question

Flying Home A bird flies from the bottom of a canyon that is 70 5 feet below sea level to a nest 7. that is 652 feet above sea level. What is the difference in elevation between the bottom of the 10 canyon and the bird's nest?

Answer 1

If we refer the level 0 to the sea level.

Then, 10 feet belox the sea level is -10 and 10 above is 10 feet (positive).

Then, the bottom of the canyon is at level y=-70 4/5 (referred to the sea level) and the nest is y=652 feet.

Then, the distance is D=y2-y1=652-(-70)=652+70=772 feet.

The distance between canyon bottom and nest is 772 feet.
