Final answer:
Options b (15 + 10 + 5), c (5 + 10 + 15), and d (25 - 5 + 10) each result in a total metric of 30 units, representing the total distance to arrive at the destination. Each option includes basic mathematical operations of addition and subtraction to find the result.
Step-by-step explanation:
The question asks us to find the total metric to reach a destination by adding up different units of distance. We will evaluate each option provided to determine which of them correctly represents the total distance.
- Option a: 10 units + 5 units + 10 units = 25 units.
- Option b: 15 units + 10 units + 5 units = 30 units.
- Option c: 5 units + 10 units + 15 units = 30 units.
- Option d: 25 units - 5 units + 10 units, which first involves a subtraction (25 - 5 = 20 units) followed by an addition (20 + 10 = 30 units).
When adding up the units, we find that options b, c, and d each give a total of 30 units, which correctly represents the total distance according to the given examples. Note that in the context of this question, the 'units' could refer to any consistent measure of distance such as steps, meters, or city blocks. Additionally, the mathematical operations mentioned (addition and subtraction) play a fundamental role in determining the total distance or total displacement when considering a path.
