Solution

Verified by Toppr

We know that the slope of the distance-time graph gives us the speed of the object. Since the slope is constant for the graph, the speed is also constant.

It means equal distance is covered by the object in an equal interval of time.

Hence, time corresponding to $3 k m$ will be $3 m i n$

$∴$ Option (C) is correct.
