Answer:
5.5
Explanation:
Solve by subtracting the two numbers:
-12.4 - (-6.9)
Note that two negative signs = one positive sign. Simplify:
-12.4 - (-6.9)
-12.4 + 6.9
Simplify. Combine the terms:
-12.4 + 6.9 = 6.9 - 12.4 = -5.5
However, note that distance cannot be a negative number, so your answer is positive 5.5
