Solution
The correct option is B
Speed of object A is smaller than object B
The slope of distance-time graph for object B is greater than the object A. Since, the slope of distance-time graph represents speed; hence, object B travels faster than object A. We do not know the magnitude of speed of object A or B and we do not know the magnitude of slopes as well. Hence, we can't say whether speed of object A is double the speed of object B.
