The diagram above illustrates the velocity-time graph of the motion of a body. Calculate the total distance covered by the body
A.
50m
B.
65m
C.
175m
D.
225m
E.
300m
Correct answer is D
Distance of A = 1/2 x (10 + 20) x 5
= 1/2 x 30 x 5 = 75m. Distance of B = 20 x 5 = 100m
Distance of C = 1/2 x 5 x 20 = 50/225
∴ Total distance is 225m
