15. While on vacation in Australia, Brent and Giselle decide to explore the Great Barrier Reef. Brent decides
to go snorkeling near the surface at a depth of 5 feet below sea level. Giselle is an experienced scuba
diver and decides to explore a little deeper at 80 feet below sea level. Represent these situations as
signed numbers.

Sagot :

The depth of diving expressed as signed numbers indicates the magnitude

and direction of Brent and Giselle's displacement in the water.

  • The situation expressed as signed number is; -5, -80

Reasons:

The depth Brent decides to go snorkeling = 5 feet below sea level

The depth to which Giselle decides to explore = 80 feet below sea level

Required:

To represent the situation as signed numbers.

Solution:

Taking the sea level as 0, we have;

The depth to which Brent goes = 0 feet - 5 feet = -5 feet

Depth at which Giselle explores = 0 feet - 80 feet = -80 feet

Expressed on the number line, we have;

-∞∣     -80∣                    -5∣                0∣                 5∣
