Amy hikes down a slope to a lake that is 10.2 meters below the trail. Then Amy jumps into the lake, and swims 1.5 meters down. She wonders what her new position is relative to the trail. Which of the following equations matches the situation above?

a. −10.2+1.5=?
b. 10.2−1.5=?
c. None of the above

To whoever answers this, thank you so much!!

Answer 1

she went down the slope 10.2 meters, -10.2

then she jumped down to the lake 1.5 meters, -1.5

-10.2 - 1.5 = -11.7 meters.

so she pretty much went 11.7 meters down from her original location.
