The V-t graph of a particle is as shown in the figure. The distance travelled by the particle in 4 seconds will be

A. 50 m

B. 55 m

C. 60

D. 65m

E. None of the above

Correct choice: B

Explanation:

The distance covered by the particle in 4 seconds
= Area enclosed by the v-t graph
= area OAB + area ACDB + area CTE + area TEFD + area EFHG
= 1/2 x 1 x 20 + (2-1) x 20 + 1/2 (3-2) x 20 - 10 + (3 -2) x 10 + (4-3) x 10
= 10 + 20 + 5 + 10 + 10 = 55 m
