1. **Stating the problem:** We are given three values: 2, 1.5 m/s, and 3.6 m/s. We need to understand what to solve with these values. Since the problem is not explicitly stated, let's assume we want to find the average velocity or check a relation between these speeds. 2. **Assuming the problem is to find the average velocity:** The average velocity $v_{avg}$ is given by the formula: $$v_{avg} = \frac{v_1 + v_2}{2}$$ where $v_1$ and $v_2$ are the velocities. 3. **Substitute the given values:** $$v_{avg} = \frac{1.5 + 3.6}{2}$$ 4. **Calculate the sum:** $$v_{avg} = \frac{5.1}{2}$$ 5. **Divide to find the average velocity:** $$v_{avg} = 2.55\ \text{m/s}$$ 6. **Final answer:** The average velocity is $2.55$ m/s. If the problem intended something else, please clarify for further assistance.
