Answer 2

Given: Velocity time graph of a body

To find: Total distance covered by body from 3rd second to 7th second

Explanation: Distance covered in a velocity- time graph is given by the area under the curve. In this graph, the shape of the curve under the curve from 3rd to 7th second is a quadrilateral called trapezium.

Area of trapezium= 1/2* sum of parallel sides* distance between the parallel sides

Sum of parallel sides= 4+10= 14 m

Distance between the parallel sides= 4 s

Therefore, area= 1/2 * 14 * 4

= 28

Therefore, the distance covered between 3rd and 7th second is 28 m.
