Answer:
Area under the speed-time graph gives the distance.
The distance covered in the time interval 0 to 20 s is equal to the area of the shaded triangle.
Area =1/2 x base x height
= 1/ 2 x (20s) x (20m/s)
= 200 m

Answer:
200 m
Explanation:
Area under the speed-time graph gives the distance.
The distance covered in the time interval 0 to 20 s is equal to the area of the shaded triangle.
Area = 1/2×base×height
= 1/2×(20s)×(20m/s
= 200m
