Answer:
Average speed = 3 ms⁻¹
Average velocity = 0 ms⁻¹
Explanation:
Total distance covered by usha in 1 minute = 180 metres
Displacement of Usha in 1 minute = 0 metres
Average speed = Total distance covered / total time taken
= 180/1 min
1 min = 60 seconds
180/60 = 3 m s⁻¹
Average velocity = Displacement / time taken
0/60 seconds
= 0ms⁻¹
The average speed of Usha is 3 ms⁻¹ and average velocity is 0 ms⁻¹
