A body travels a distance of `2 m` in `2` seconds and `2.2m` next `4 seconds`. What will be the velocity of the body at the end of `7` the second from the start?

Explanation

To solve the problem, we need to determine the velocity of the body at the end of the 7th second. We will break this down step by step.

### Step 1: Calculate the average velocity for the first segment of motion
The body travels a distance of \(2 \, \text{m}\) in \(2 \, \text{s}\).

Using the formula for average velocity:
\[
v_1 = \frac{d_1}{t_1} = \frac{2 \, \text{m}}{2 \, \text{s}} = 1 \, \text{m/s}
