Question

A deep-sea diver is 4.5 m below the water level . At what depth is he now? At what height is he now? Note: The mean sea level is considered to be the zero level.

Answer 1

Depth= sea level - his distance according to water level
= 0- (-4.5) m
= 0+ 4.5 m
= 4.5 m

His height = sea level + his distance according to water level
= 0+ (-4.5)m
= (-4.5)m

Answer 2

Answer:

Depth=4.5m and hight = (-4.5)m

Step-by-step explanation:

Depth =sea level (0) - his distance according of the water level.

=0-(-4.5)m

=(-×-=+) 0+4.5m

=4.5 meter depth

His hight= sea level (0)+his distance according to water level.

=0(water level)+(-4.5)m

=(-4.5)m
