Answer: velocity in m/s=0.4166m/s
time=21.603s
Explanation:Displacement=9m
Velocity=1.5km/h=(1000/3600) m/s
=5/18m/s
To convert km/h to m/s, just multiply the given value of km/h by 5/18
1.5km/h=1.5×5/18=0.4166m/s
now velocity =displacement/time
time=displacement/velocity
=9/0.4166
=21.603s
Hope it helps
