The Velocity-Time graphs of the two cars, K and I are given
below together. If the cars start their journey together and they
have a position difference of 10 m at time t, what will be the
position difference between them at time 4t at the end?

The position difference between them at time 4t is 10m.

Explanation:

A velocity-time graph illustrate the movement of an object from one location to another given some of its parameters. The slope of the graph gives the acceleration of the object, and the total area under the graph gives the total distance covered by the object.

From the given graph, the starting points for both cars are not the same neither their stopping point. Initially, the starting position difference between the cars is 10m. The position difference between them at time 4t at the end is 10m.
