The displacement-time graph for two particles is as shown. Find the ratio of their velocities.

Explanation

To find the ratio of the velocities of two particles based on their displacement-time graph, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Displacement-Time Graph**:
- The displacement-time graph shows how the displacement (S) of two particles changes over time (t). The slope of the graph at any point gives the velocity of the particle.

2. **Identify the Slopes**:
...
