Answer 1

Total displacement of the particle = Area under the velocity-time graph = 1/2 × 100 × 100 m
=5000m
Total time taken = 100 sec
Therefore average velocity during the journey= Total displacement of the particle÷ Total time taken= 5000÷100 sec = 50m/sec

Therefore average velocity during the journey= 50m/sec.
