Answer:
(a) Average speed = Total distance covered / Total time taken
= 250m + 50m / 1 min 40 s + 30 s
= 300m / 130 s
= 30/13
= 2.3 m/s
(b) Average velocity = Total displacement / Total time taken
= 200 m / 130 s
= 1.5 m/s

Answer:
a) Average speed = Total distance covered / Total time taken
= 250m + 50m / 1 min 40 s + 30 s
= 300m / 130 s
= 30/13
= 2.3 m/s
(b) Average velocity = Total displacement / Total time taken
= 200 m / 130 s
= 1.5 m/s
Explanation:
a) Average speed = Total distance covered / Total time taken
= 250m + 50m / 1 min 40 s + 30 s
= 300m / 130 s
= 30/13
= 2.3 m/s
(b) Average velocity = Total displacement / Total time taken
= 200 m / 130 s
= 1.5 m/s
