Question

Edward is scuba diving. He stops 14.3 m below the surface to look at a fish. Then he swims up 3.2 m. Which is the best approximation of Edward's current position relative to the ocean surface?
A.) 12 meters
B.) 11 meters
C.) -17 meters
D.) -23 meters
Dara chose B as the correct answer. How might she have gotten that answer?

Answer 1

11 meters because if you do 14.3-5.8=8.5 then it said he went up so now you do 8.5+3.2=11.7 but instead of rounding up she rounded down (I think that’s the answer)
