A man starts from his home at `8.00` am to his office. He walks with a speed of `2 ms^(-1)` on a road upto his office `3.0 km ` away from his hom. He stays in the office upto `4.00 pm` and returns to his home by which moves non-stop with a speed of `10 ms^(-1)`. Calculate
(i) the time taken by man to reach his office and
(ii) time taken by man to reach his home. Also plot `x-t` graph of his motion.

Explanation

To solve the problem step by step, we will break it down into two parts: calculating the time taken by the man to reach his office and the time taken to return home. Finally, we will plot the x-t graph of his motion.

### Step 1: Calculate the time taken to reach the office

1. **Identify the distance to the office**:
- The distance from home to the office is given as 3.0 km.
- Convert this distance into meters:
\[
