(2) 30 m
(3) 40 m
(4) 50 m​

Answer 1

Explanation:

The distance or displacement travelled by a particle in v-t graph is area under the graph this v-t graph has 2 triangles and a rectangle ,

=> first triangle(1/2×b×h)

=1/2×3×20

=30m

=>rectangle(l×b)

=20×1

=20m

=>second triangle(1/2×b×h)

=1/2×1×20

=10m

total distance = (30+20+10)m

= 60m

therefore option a is correct
