DISTANCE = AREA UNDER VELOCITY-TIME GRAPH
DISTANCE IN FIRST 10 SECONDS:
AREA OF TRIANGLE = 1/2 × B × H
1/2 × 10 × 20 = 100
DISTANCE IS 100M
DISTANCE FROM 10 TO 30 S
AREA OF RECTANGLE = L×B
20 × 20 = 400M
DISTANCE FROM 30 TO 40S
AREA OF TRIANGLE 1/2 × B × H
1/2 × 10 × 20 = 100M
TOTAL DISTANCE COVERED = 100 + 400 + 100 = 600M
PLEASE MARK AS BRAINLIEST
AND A HAPPY JANMASHTAMI
