To find the total movement of the fault line over the past two years, we need to add the two movements together:
- The movement in the first year:
inches - The movement in the second year:
inches
First, let's convert the mixed numbers into improper fractions.
-
For
: -
For
:
Now, we need to add
Next, let's convert both fractions to have a denominator of 10:
-
For
: -
For
:
Now, we can add the two fractions:
Next, we can convert
Thus, the total movement of the fault line over the past two years is:
