Figure shows the displacement-time graph of two vehicles A and B moving along a straight road. Which vehicle is moving faster? Give reason.
Vehicle A is moving with a faster speed because the slope of line A is more than the slope of line B.
Concept: Distance and Displacement
Is there an error in this question or solution?
Vehicle A is moving faster than vehicle B.
Speed is given by the relation
Speed = `"Distance covered"/"Time taken"`
This relation shows that speed of a vehicle is greater if it covers maximum distance in a given interval of time. To compare the distance, draw a line perpendicular to the time-axis, as shown in the following distance-time graph
From the graph, it is evident that for a given time t, the distance covered by vehicle A is more than vehicle B. Hence, vehicle A is moving faster than vehicle B.
