What is an example of Mid-Ocean Ridge

Mid-ocean ridges form where two tectonic plates are pulling apart, also called seafloor spreading. ... The Mid-Atlantic Ridge, which is spreading one to two inches a year, along with the East Pacific Rise, which is spreading two to six inches a year, are two examples of very long mid-ocean ridges.

Explanation:

a, b, c - sides of a triangle

a + b > c

a + c > b

b + c > a

we have a = 5m and b = 11m. substitute:

5 + 11 > c

16 > c → c < 16

5 + c > 11         subtract 5 from both sides

c > 6

11 + c > 5         subtract 11 from both sides

c > -6

c < 16 and c > 6 and c > -6

thereofre your answer is 6m < c < 16m

d would be your answer
