Answer:
a) Distance covered = Area under curve
Distance covered by car P
= Area of ∆ PCA
= 1/2 x Base x height
= 1/2 x AC x PC
= 1/2 x 4 x 6
= 12 m
Distance covered by car Q
= Area of Rectangle ACQD
= Base x height
= AC x AD
= 4 x 3
= 12 m
Hence, there is no difference in the distance travelled by both cars P and Q in 4 seconds.
b) Car P is moving with constant acceleration and Car Q is moving with constant speed.
