In the given v-t graph the distance travelled by the body in 5 second will be

A

100 m

B

80 m

C

40 m

D

20 m

Answer

100 m

Explanation

Solution

The distance is equal to total area under v-t graph=20×22+20×2+20×1+20×12+20×12= \frac{20 \times 2}{2} + 20 \times 2 + 20 \times 1 + \frac{20 \times 1}{2} + \frac{20 \times 1}{2}

= 20 + 40 +20 +10 +10 = 100 m
