Question

Trina and Jessie went on a vacation to Hawaii. Trina went scuba diving and reached an elevation of −85.6 meters, which is below sea level. Jessie went hang-gliding and reached an altitude of 87.9 meters, which is above sea level. Who is closer to the surface of the ocean?

Answer 1

Explanation:

LEt the surface of the ocean be at the zero level i.e at 0metres

If Trina went scuba diving and reached an elevation of −85.6 meters, which is below sea level, the distance between Trina and the sea level will be:

D = 0-(-85.6)

D = 0+85.6

D = 85.6m

If Jessie went hang-gliding and reached an altitude of 87.9 meters, the distance between Jessie and the sea level will be:

D = 87.9-0

D = 87.9m

Since the distance of Trina is less than that of Jessie, this means that Trina is closer to the surface of the ocean
