Speed is distance traveled per block of time. As an equation, this is
Speed = distance/time
In your problem, the given distance is 300km, and the time is 2.5 hours.
Plugging into the equation,
Speed = 300km / 2.5 h
Speed = 120 km/h
Velocity is speed <em>and</em> direction.
The velocity would be 120 km/h north.
I think it’s the last one I am not sure tho
0.25 in a fraction would be 1/4
Volume = (edge)^3
Volume = (3/4)^3
Volume = (27/64) inches^3
Done.
