The diagram above shows a velocity time graph representing the motion of a car. Find the total distance covered during the acceleration and retardation of the motion

A.

75m

B.

150m

C.

300m

D.

375m

Correct answer is D

Total Distance covered is the Area of the Trapezium

Area of the Trapezium = \(\frac{1}{2}\) X ( sum of parallel sides ) X height

=  \(\frac{1}{2}\) X ( 30 + 45 ) X 10

: S = 375m
