Explanation:
The average velocity is in attachment
Average speed I have text down
time travelled in North = 2sec
speed in North = 4m/s
distancs covered in North = speed × time
= 4 ×2 = 8m
time travelled in West = 6sec
speed in West = 1 m/s
distance covered in South = 6sec × 1 =6m
total time = 2sec + 6sec = 8sec
Total distance = 8m + 6m =14m
Average speed = total distance/total time
= 14/8 = 7/4 m/s
