Four cars A, B, C and D are moving on a levelled road. Their distance versus time graphs are shown in Figure. Choose the correct statement

(a) Car A is faster than car D.

(b) Car B is the slowest.

(c) Car D is faster than car C.

(d) Car C is the slowest.

Answers (1)

Ans. B

Sol.

If we closely observe the graph, we will notice:

For any time interval distance travelled by car C is maximum followed by D, A and B.

Hence, car C is the fastest car and car B is slowest car.

In distance time graph, if the graph is a straight line then the angle between the straight line and time axis represents the slope or velocity of the car.

Larger the angle implies larger the slope means larger velocity.

Hence the correct option is B.
