In this scenario, the figure represents a time-velocity graph of a moving body. To determine the distance covered, we need to calculate the area under the graph.

Option 1 suggests that the body covers 30 metres. However, the graph shows a larger area, so this option is unlikely to be correct.

Option 2 suggests that the body covers 40 metres. Again, looking at the graph, it appears that the area under the graph is larger than 40 square units. This option seems incorrect.

Option 3 suggests that the body covers 50 metres. This seems to be a reasonable estimate based on the graph. The area under the graph could indeed represent a distance of 50 metres. Therefore, option 3 is the correct answer.

Option 4 suggests that the body covers 60 metres. Although the graph does show a larger area, it does not seem to be as large as 60 square units. Therefore, option 4 is also unlikely to be correct.

So, based on the information provided and the graph displayed, option 3, which states that the body covers 50 metres, is the most accurate answer.
