Answer:

|-3.9-(-15.1)|=11.2

Step-by-step explanation:

the last one is the answer

Lets check one by one

#1

  • |-15.1+(-3.9)|
  • |-15.1-3.9|
  • |-19|
  • 19

Wrong

#2

  • -15.1-3.9=-19

Wrong

#3

  • -3.9-15.1=-11.2

Still wrong

#4

  • |-3.9-(-15.1)|
  • |-3.9+15.1|
  • |-11.2|
  • 11.2

Distance must be positive so it's correct
