The given speed is = 8.8 meter per second
To convert it in kilometer per hour, we will do the following steps:
1 meter = 0.001 km
So, 8.8 meter = 0.0088 km
3600 seconds = 1 hour
1 sec = [tex]\frac{1}{3600}[/tex] hours
now, [tex]\frac{8.8meter}{second} = \frac{0.0088}{\frac{1}{3600} }[/tex]
Now multiplying 0.0088 and 3600
[tex]0.0088*3600[/tex]
= 31.68 km/h
