Question

A scuba diver uses negative numbers to represent her depths below sea level. She was at a depth of -1.5 meters. A few minutes later she continued another -4.2 meters to the ocean floor below. What was her final depth?

Answer 1

Answer:

Step-by-step explanation:

Depth in which scuba diver is in first time = -1.5 m

depth in which scuba diver is in second time = -4.2 m

Her final depth = -1.5 + (-4.2) m

                         = -1.5 -4.2 m

                         = -5.7 m
