Consider a situation where you exert a force F on a crate of mass m, moving it at a speed v a distance d across a floor in a time interval t.
-The power you supply to the crate is Fd/t.

According to the formula for power, P = W/t = (Fd cosθ)/t, where θ is the angle between the force and displacement vectors. In this case, since the force is applied in the direction of motion (i.e. θ = 0), we have P = Fd/t. Therefore, the statement is true.
