An insect starts from a point and travels in a straight path 1 mm in the first second and half of the distance covered in the previous second in the succeeding second. In how much time would it reach a point 3 mm away from its starting point.

Explanation

To solve the problem step-by-step, we will analyze the distance traveled by the insect over time and determine if it can reach a point 3 mm away from its starting point.

### Step 1: Determine the distance traveled in each second.
- In the first second, the insect travels **1 mm**.
- In the second second, it travels half of the distance covered in the first second:
\[ \text{Distance in 2nd second} = \frac{1}{2} \times 1 = \frac{1}{2} \text{ mm} \]
