Ineed don't understand this problem. trina  and jessie went on vacation. trina went scuba diving and reached an elevation of -85.5 meters, which is below sea level. jessie went hang gliding and reached 87.9 meters which is  above sea level. who is closer to the surface of the ocean? explain? trina wants to hang glide at the same number of meters above sea level as she scuba dived below sea level. will she fly higher than jessie did? explain?

I will explain this answer with the help of number line which i have shown below.

Considering sea level as starting point i.e origin i will depict how far Trina had gone below sea level and how much Jessie went above sea level.

Distance Traveled by Trina below sea level = - 85.5 meter

Distance Traveled by Jessie  above sea level =87.9 meter

Considering sea level as origin i.e 0

Total distance traveled by Trina= 0-(-85.5)=85.5 meter

Total distance Traveled by Jessie = 0+87.9=87.9 meter

So,Trina is nearer to sea level than Jessie.

Now Trina wants to hang glide at the same number of meters above sea level as she scuba dived below sea level.

Then Distance traveled by Trina=85.5 meter

No,she will not fly higher than Jessie because Jessie has traveled 87.9 meter.

- 70
