Question

State how the velocity-time graph can be used to find the distance travelled by the body in a given time.

Answer 1

Distance travelled from velocity-time graph
The total distance travelled is the arithmetic sum of the area enclosed between velocity-time graph and time axis, without considering the direction of displacement.​ Here, the total distance travelled (between​ t= 0 s and t= 20 s) = Sum of areas = 30+10​ = 40 m.
