Answer:
Option A.
Step-by-step explanation:
It is given that Mona is hang gliding 5/4 kilometers above sea level. Directly below her, she sees a whale 0.2 kilometers below sea level.
Distance between Mona and sea level = 5/4 km
Distance between whale and sea level = -0.2 km
"+" sign represents the distance above sea level.
"-" sign represents the distance below sea level.
[tex]\text{Total distance}=\dfrac{5}{4}-(-0.2)[/tex]
Take modulus because distance can not be negative.
[tex]\text{Total distance}=|\dfrac{5}{4}-(-0.2)|[/tex]
Therefore, the correct option is A.
