From the table, we observe that as $$x$$ increases, $$y$$ decreases. This type of variation is called indirect variation, Here, $$xy=120$$ Thus, $$y=cfrac{120}{x}$$ Plot the points $$(2,60),(4,30),(6,20),(10,12)$$ and $$(12,10)$$ Join these points by a smooth curve. From the graph, we have (i) The number of hours he needed to travel at a speed of $$5km/hr$$ is $$24$$hrs. (ii) The required speed to cover the distance in $$40$$ hrs is $$3km/hr$$
