Set 2: Linear Equations (Intermediate)

Choice D is correct. Choice D is the correct answer. 1. Define: Time B = $t$, Time A = $t + 2$. 2. Distance Equal: $6t = 3(t + 2)$ 3. Simplify: $6t = 3 t + 6$ 4. Subtract 3 t: $3t = 6$ 5. Divide by 3: $t = 2$ 6. Verify: $12= 3(4) = 12$ ✓ Choice D is incorrect because it results from an error in the solution process. Choice A is incorrect because it results from an error in the solution process. Choice C is incorrect because it results from an error in the solution process.
